Fourth wall

''' "What? What's a Wii Remote? ...Don't worry. As long as the player gets it, we're fine."

- Garson

Sometimes, characters from the Mario series will state something that implies that they are aware of being fictional characters in a video game; this is known as breaking the fourth wall. The reason it is called a "fourth wall" is that the term originated from plays in theaters, when actors would look at the audience, talk to them, or do anything else that involved the audience. Because the stage would generally have a wall at the back and both sides, this concept involves the actors becoming involved with the audience who are at the front, which can be considered an invisible wall, making it the fourth one.

''Note: Video games frequently break the fourth wall in order to address the player with directions (i.e., "Press A to jump"). These instances are not to be recorded here, unless the characters are aware they are in a video game due to the remark.''

Super Mario Bros: The Lost Levels
In the final level of World 9, a group of tile blocks can be found spelling out "アリガトウ！" (Arigato!, meaning "Thank You" in Japanese). Also, the opening of World 9-1 features a message saying "WE PRESENT FANTASY WORLD. LET'S TRY '9' WORLD WITH ONE GAME.", and the Game Over screen for World 9 has a message saying "YOU'RE A SUPER PLAYER! WE HOPE WE'LL SEE YOU AGAIN. MARIO & STAFF."

Super Mario World
After the Yoshi Eggs hatch during the ending sequence, the words "THANK YOU" appear as Mario gives the V for victory sign to the player while Princess Toadstool (or Peach in the GBA remake) waves to him or her. At the end of the remake, Super Mario World: Super Mario Advance 2, there is no text, though the princess still waves at the player and Mario and Luigi will still flash the peace sign. In the last level of the Special World, Funky, a group of coins spell out the phrase, "YOU ARE A SUPER PLAYER!" near the end of the level (in the Japanese version, the coins spelled "YOU ARE SUPER PLAYER!").

Super Mario 64 / DS
At the game's title's screen, Mario will speak to the player with lines such as "It's-a-me, Mario! Hello!" and "Press Start to play!". At the ending sequence, Mario (or Yoshi in the remake) points his face to the player.

In the two versions, after Bowser is defeated in Bowser in the Sky, he will exclaim, "C'mon, troops! Let's watch the ending together! Gwa ha ha!" Additionally, if Mario retrieves all 120 Power Stars and then defeats Bowser, the Koopa King will say, "Just you wait until next time. Until then, keep that Control Stick smokin'! Bwaa ha ha!" In the case of Super Mario 64 DS, Bowser says the same thing after all 150 stars are collected, however he mentions the Touch Screen instead of the Control Stick, as the Nintendo DS does not feature a Control Stick.

After the end credits in both versions, Mario is heard saying, "Thank you so much-a for playing my game!" He uses the same phrase in Super Mario Galaxy and its successor, Super Mario Galaxy 2.

In the N64 version, after Mario collects all 120 stars, shoots to the top of the castle and talks to Yoshi, he gives Mario the following message: "Thanks for playing Super Mario 64! This is the end of the game, but not the end of the fun. We want you to keep on playing, so we have a little something for you. We hope you like it! Enjoy! --The Super Mario 64 Team"

In the case of Super Mario 64 DS, upon closing the Nintendo DS while playing, Mario says "Buh-bye!" to the player, after which the system goes into standby. When the system is opened, he says "It's-a-me, Mario!"

When the player defeats King Bob-omb in Bob-omb Battlefield, King Bob-omb will say "Just select this star from the menu. For now, farewell."

Super Mario Sunshine
After Mario defeats Bowser and Bowser Jr., a certain yellow Pianta in Delfino Plaza will ponder whether the game is over and express his hopes of something else happening when Mario talks to him.

New Super Mario Bros.
In the intro, when Mario is hit by the green shell, the words "Super Mario Bros." fall from the sky. A few seconds later, Small Mario runs near it, notices it isn't straight, and jumps to hit the words and straighten them, also causing "New" to appear next to "Super". This only happens after waiting a few seconds on the title screen.

After the end credits, the Touch Screen shows Bowser Jr. dragging his unconscious father back to their home. Bowser Jr. looks to the camera and threateningly growls at the player. He then resumes dragging Bowser.

Similar to Super Mario 64 DS, Mario will also say "Buh-bye!" to the player when closing the Nintendo DS. He also says "It's-a me! Mario!" when the player opens the DS and resumes the game, similar to the opening title screen in Super Mario 64 and similar to that in its remake.

The enemies and power-ups do a small dance when there is a little "bah bah" vocal in the music, such as a Goombas jumping up in the air and Koopa Troopas will turn to the screen for a split second and rock their fists. This actually affects gameplay, as a Goomba jumping at the wrong moment could result in the player hitting a Goomba in the face rather than its head, or the player could fall short of a Koopa Troopa due to it stopping for a moment.

Super Mario Galaxy
Much like the ending to Super Mario 64, after the credits roll, Mario or Luigi will say "Thank you so much for playing my game" (Luigi, however, removes the "so much" part of the sentence). When 120 Power Stars are collected, after Mario or Luigi thanked the player, Rosalina will also thank the player and says "May the stars watch over you."

New Super Mario Bros. Wii
When Bowser's Airship takes off without Bowser Jr. aboard, he faces the player with a surprised look. He will also look surprised at the player if all the characters bubble or one of them bubbles and the other three take a Warp Pipe.

Also, in the credits, the players play a minigame where they break blocks to earn coins. These blocks have the credits written on them. If less than four players are playing, the characters not controlled will dance to the music.

The enemies still do a dance to the "bah bah" vocals in the music.

Super Mario Galaxy 2
If the player's Wii Remote batteries are low, and they talk to Lubba, he will warn the player about the batteries running out in a dangerous place. He will frequently make these kinds of references, such as suggesting that the player go to bed when it is late, or to turn off the game after a certain playing time, especially after getting a Game Over, or tell the player to take a break before playing again. Additionally, if the player plays the game at an early time, Lubba will say he is sleepy and that it is rather late to be adventuring.

Sometimes, when the player gets extra lives while there are either two or three save files in the game, Mailtoad says "So this person you share a special bond... Could it be someone from another save file?".

Before the battle with the Whomp King in Throwback Galaxy, he will say "Let's see you try and ground-pound the Whomp King again!" which means he is the same Whomp King that Mario fought in Super Mario 64. He will also try and say his opening lines he used in Super Mario 64, but before saying he is tired of this speech.

If the player has 70 to 120 Power Stars, then at the end of the credits, Mario says "Thank you so much for playing my game", much like in the previous game and Super Mario 64 and Super Mario 64 DS. When playing as Luigi, he will say the same thing as its predecessor.

If the player gets a Game Over or goes to a world for the first time, Lubba will speak to the player.

Super Mario 3D Land
When Mario/Luigi completes a level, they will face the player.

When Mario finds Peach at Bowser's Castle, Bowser falls from the ceiling and punches the ground, cracking it. When the ground is about to break, Bowser faces the screen with a worried expression on his face.

If the player continuously keep on losing lives or plays for a long time, a notification tells the player to take a break.

In Special 8-Crown, a group of Snake Panels near the end can be activated to spell out the phrase "THANK YOU!!" similar to other thanking messages in Super Mario Bros: The Lost Levels and Super Mario World.

New Super Mario Bros. 2
Near the end of the game intro, Ludwig von Koopa uses his magic wand to make the title and multiple coins fall from the sky. This only happens when watching the intro after a few seconds on the title screen.

In the credits, Roy Koopa hangs off the D of EAD with his tail.

After Bowser's battle in the Gold Classics Coin Rush pack, many coins form the sentence "THANK YOU!!" once again.

The enemies still do a dance at the "bah bah" vocals.

New Super Mario Bros. U and New Super Luigi U
On the title screen, the characters ground pound to make the title and two Super Acorns appear.

If the characters are idle, they stare at the screen. Baby Yoshis have an added choir to all the music that they mouth to.

In the credits, the characters not being played dance to the music, and when a character being played runs near the credit letters, they spin around.

The enemies still do a dance to the vocals.

Super Mario 3D World
When the player starts up the game, Mario and his friends yell out "Super Mario 3D World!"

The flowers and bushes move along to the music.

The Green Sprixie Princess waves to the screen near the end of the credits scene.

Upon completion of Bowser's Lava Lake Keep for the first time, once the transition occurs, shortly after, Bowser's laugh can be heard as he pulls back the transition to reveal that he has captured the sprixies once more.

At the end of Champion's Road is a series of Clear Pipes forming the message "THANK YOU!!" just before the Goal Pole area.

Donkey Kong series
Throughout the series, whenever the player visits Cranky Kong he constantly remarks about how the games of yesteryear are superior to modern games, and often whines about how the game that he's in is too easy for someone like him to complete. The instruction booklets also contain even more remarks of this nature.

Donkey Kong Country 3: Dixie Kong's Double Trouble!
If the Kongs manage to find Krematoa without speaking with Blunder, he will say "I can't believe you found the Lost World on your own! I bet you cheeky so and so's used Nintendo Power's guide! I know I did!"

Donkey Kong Barrel Blast
If the player hovers over the "Back" button on the main menu, Diddy Kong will arrive and wave goodbye to the player.

Super Mario World 2: Yoshi's Island
In a secret area in Jungle Rhythm..., there is a Message Block that gives the message "We, the Mario team poured our hearts and souls into creating this game for your entertainment. It is full of secrets. Enjoy!". In the Game Boy Advance remake, the message is changed to "'How do you like this game? Goodies are hidden in every level, you know. You should look all over if you want to get 100 points! Investigate anything that looks suspicious.".

Yoshi's Island: Super Mario Advance 3
If the player gets a perfect score in every stage, a message comes up saying "Congratulations! What an amazing job! You are the _____st Yoshi to adventure on Yoshi's Island."

Yoshi's Story
Each time the player eats a Heart Fruit after playing a level's minigame, a row of Coins forming a letter will appear. If the player puts all the letters from each level in order, it reveals the message "YOU ARE YOSHIS GREAT PARTNER!"

Yoshi's New Island
If Yellow Yoshi is hit by a hammer in Fort Bucket Booby Trap, he will be knocked into the screen and slide down it.

In the microgame "High-Speed Chase", if the player fails to run from the chasing object, Wario will be sent towards the screen, breaking it.

Game & Wario
In the minigame Ashley, Ashley will tell the player 'You with the GamePad! You're gonna have to guide me.'

Also, if the player blows on the GamePad, Ashley tries to cover her skirt as it goes up and will give the player an angry look.

In the minigame Wario's Homerun Derby, if the player hits a home run, the ball will be sent toward the screen, breaking it.

In the manual, Wario complains about his transformations caused by enemies and blames the developers.

Wario World
In Wario World, Wario states "So admit it..... Don't I look cool in the game screens? Those long, muscular legs on my sturdy toned frame.... I'm the perfect specimen of a man ..... What!?!? You say I look fat and my quadruple chin looks like a waterfall of flab? Shut up! That's just because you have your television set up on widescreen display!"

Whenever the player pauses the game, Wario will constantly sing, "Na Na Na Na Na Na!" If the player listens long enough, Wario will eventually say, "Sorry" and stop singing.

Wario's Woods
In the SNES version of Wario's Woods, after defeating the player in the VS. COM mode, Sven will tell Toad that he was "glad that [the player] didn't reset the game when he saw it was hopeless."

Mario Golf (Nintendo 64)
At the end of the game's intro, Wario's voice is heard quietly saying, "It should've been called Wario Golf. ...You're gonna love it!"

Mario Golf: Toadstool Tour
Most celebrations have the characters facing the screen at the end of each hole. As an example, whenever Waluigi gets an Eagle or better, he will dance and spin all across the green until he points to the player, turning around upon realizing he is pointing the wrong way. Prior to the opening, Wario and Waluigi hold up signs for both Nintendo and Camelot respectively. This also occurs at the start of Mario Power Tennis.

Mario Golf: World Tour
This is done in the same manner as in the previous game. For example, if Bowser gets an Eagle or better, then he'll run to the screen and breathe fire, or punch the screen if he gets a Bogey or worse. This is also likely due because of a Lakitu holding a camera, but he is not seen anywhere.

Mario Party 3
If the player completes Story Mode with all S's, the Millennium Star will tell the player, "You're spectacular. Truly spectacular. I imagine the development staff of Mario Party 3 is pleased as well. Keep up the good work."

After MC Ballyhoo is concerned with Bowser having stolen the Star Rod, he says, "But wait! We have YOU!", referring to the player.

Mario Party 9
On the main menu, Yellow Toad speaks to the player.

When Toad or Wario are chosen on the character selection screen, they might say, "Good choice".

When the players land on a Bowser Space, Bowser roars, and it breaks the screen. This doesn't happen on Bowser Station.

In some of the Superstar celebrations, the characters will do something that makes them face the screen. An example is at the end of Magikoopa's, when he points his wand to the screen.

Mario Party 10
When a character releases Bowser with all of the numbers on the Dice Block, Bowser appears by slashing through the screen with his claws. This also applies to the end of the Bowser Battle minigames during Bowser Party and amiibo Party as well as the North American commercial showing the gameplay for Bowser Party.

Mario Kart 64
After the credits, Mario will say; "Hey, you're very good! See you next time!"

Mario Kart 7
After the credits, Mario shouts "Thanks for playing! Way to go!" or "Thanks for playing! You're the best! Ha ha!" depending on how much the player has progressed during the game, and the default characters or all of the characters wave to the player, including his or her own Mii.

Mario Kart 8
In Toad's Turnpike, trucks with Mario Kart 8 on the back and sides can be seen.

Additionally, some tracks feature posters of the Mario Kart 8 cover.

Paper Mario
If Goombario uses Tattle on a Goomba, the tattle mentions that they have been around since Super Mario Bros..

While Mario is fighting Bowser???, the Koopa Bros. try to lower his confidence by telling him that the phony Bowser is invincible. One of the things they say is "The sequel should be called Paper Bowser!"

When Mario wins a battle, sometimes he looks at the player and give them a thumbs up. This also happens in the sequel and Sticker Star.

At the beginning of the fourth fight, Jr. Troopa actually notices his HP bar when it has dropped to half, and comments that he lost his HP due to swimming across the ocean.

At the end of the game, a Bumpty mentions that Herringway plans to write about Mario's story, coming up with the title "Paper Mario".

Paper Mario: The Thousand-Year Door
If Mario gets in Danger while fighting Gus, he'll break the fourth wall by acknowledging that "…it'll be Game Over for you!" and that the player can choose their Tactics menu.

After Mario defeats Gus, he will shout, "CRUD! You dumb video-game heroes always do this!"

A young Toad in the Petal Meadows village will say: "There's this one game that just absolutely rules. It's called 'Fire Emblem'...". This reference was shortly before the international release of Fire Emblem: Rekka no Ken, the first game in the series to be released outside Japan and seventh installment overall. Paper Mario and Fire Emblem are both developed by Intelligent Systems. In the Japanese version of the game, the Toad kid mentions Super Mario Bros. for the Famicom instead.

After rescuing Koopley from Hooktail, Koops says: "For ten long years we all thought you'd...you know! We thought your game was over!"

While describing how the Happy Lucky Lottery works, Lucky will explain that the daily number changes every day in real-time and that he uses the Nintendo GameCube's clock as a reference. If the player sets the GameCube's date back in an attempt to cheat the system, Lucky will penalize them.

When Goombella tattles on Stewart in Glitzville, she will tell Mario that Cheep Cheeps have been a part of the Mario franchise for a while. In fact, Goombella even says, "Oh, gosh. I just broke through the fourth wall there, didn't I? Sorry. Just forget it."

The same occurs when she tattles on the gatekeeper of Twilight Town, in which she says that the game would be too easy without him. Rather than directly referring to breaking the fourth wall, she only says, "Hee hee... Let's never speak of it again."

Koops breaks the fourth wall after the fight with Doopliss where he says "Sort of easy for a boss battle as it were." Unlike Goombella though, he doesn't seem to notice that he broke the fourth wall. Doopliss also breaks the fourth wall during the chapter by removing the lowercase p from the naming screen.

Just before Mario begins Chapter 5, Professor Frankly is about to tell them very important and long information concerning the Thousand-Year Door. He asks if they're ready to hear it, and then says, "And you there! In front of the TV! You listen up, too!". Mario's current partner out will question Professor Frankly (for example, Yoshi says to him, "Did someone pile-drive your head, or what? I don't see any TV here, nutjob!". Vivian remarks, "What to say... ARE YOU TALKING TO NO ONE?!?" Goombella even says, "Yeesh. First me, then you! Why do we always have to break through the fourth wall?") Frankly yells at them, saying to disregard it as he continues. Later during the chapter, Lord Crump (under his alias, "Four Eyes") tells the player that they'd better not tell Mario who he really is, though it is impossible to even use Mario to attack him until the end of the chapter.

After Chapter 6, when Bowser makes it to Rawk Hawk's secret training facility, Rawk Hawk appears. As soon as he appears, he points at the camera insultingly asking the player if they forgot him.

A Toad in Petalburg consistently breaks the fourth wall throughout the game. He states that he is a fan of Luigi and says he wants a game called "Paper Luigi". Later, he mentions that he is actually playing the game Paper Mario: The Thousand-Year Door and ends up beating it before the player does. In every chapter, he always talks about a different Nintendo game.

In the Palace of Shadow, if Mario allows the Dry Bones to force him to the center of the room, Mario's partner will warn him that the floor will swallow them up. If Mario does not move to prevent this, his partner will scream that they are doomed. If Yoshi is Mario's partner at the time, he will say, "Awww, game over, man! WHOOOOOOOOOOOAAAAAAA!"

After completing Chapter 6, a young Toad will appear in Cabin 007 of Excess Express. If Mario (controlled by the player) talks to him, he will ask Mario a quiz: "What did Bowser nab in the last Paper Mario?" The options are "The Star Cookie", "The Star Rod", and "Someone's Lunch".

In Chapter 3, Hamma Jamma says that 7-1 was his grandfather's 'hood'.

Super Paper Mario
Several characters, the first one being Bestovius, refer to a certain button when explaining how to perform an action. When Mario asks what they mean by pressing that certain button, the character assures them not to worry, and that the great being that watches them (the player) will know what it means. For example, when encountered, Thoreau says: "What's this, you say? You need not worry. The great being that watches us will know what it is." However, during Garson's story "Stylish Moves," he states that Mario can perform one by shaking the Wii Remote; when Mario asks what the remote is, Garson replies, "What? What's a ? ...Don't worry. As long as the player gets it, we're fine," outright stating the existence of the player instead of alluding to them.

Before fighting him in Chapter 3-1, Bowser shouts to Mario, "No more sequels!" and that he will finish him off, describing himself as "Grade A, 100% prime-cut final boss." Later, during Chapter 3-4, the last option for Princess Peach to choose on the Swoon.exe will result in her to outburst in anger and demand to know who is picking these answers for her.

The Sammer Guy Mystical Whistle claims that no one can beat him without using hacks, a reference to players who use cheat codes and devices to make games easier. Another Sammer Guy named Invisible Brock claims that no one could find him without using a game guide.

The Underwhere itself is a break in the fourth wall, because its inhabitants say that their game had ended. As with the rest of the series, death is referred to as getting a game over.

Paper Mario: Sticker Star
Mariachi Guys will play their instruments to the music when Mario gets close to them. When the player saves Traveling Toad in Drybake Desert, he admits he wants to leave because there is "this weird music that never stops". This is probably referencing to the background music, and the added instruments from the Mariachi Guy near him. Also, when the player fights Gooper Blooper, his tentacles clap along with the music.

When Mario uses a Slaphammer sticker and manages to do an "Excellent" move, the enemy will be flung in the air, and crash into the screen.

When Mario stays still, the HP bar shows up and if one were to blow in the microphone, it would sway from the left to right.

When the player moves their 3DS, Shiny, Flashy, Big Shiny, and Megaflash stickers will shimmer.

Mario & Luigi: Superstar Saga
When Bowser's Castle plunges into the ocean, Bowser hits the screen, cracking it.

In Mushroom Plaza, when Mario talks to the Toad by the fountain he'll ask Mario if he wants to hear about Action Commands. If Mario says no every time, the Toad will say "Action Commands are... Well go read the instruction booklet!"

In an area of the Woohoo Hooniversity that contains no enemies, but several objects to be studied, there is one room with four blocks in it: One from Super Mario Bros., one from Super Mario World, one from Super Mario 64, and one from Paper Mario. If Mario or Luigi strikes the block, they will read a description of the block, which says what game it's from. (i.e. Block used in Super Mario Bros.)

Mario & Luigi: Partners in Time
Mario breaks the fourth wall in Shroob Castle by noting to Luigi that the adult brothers and the baby brothers must stay on the bottom screen.

Mario & Luigi: Bowser's Inside Story
After beating the game and after the cake picture, Chakron will directly compliment the player.

The last one of Bowser's ranks is Final Boss, referencing that Bowser is the final boss in most Mario games.

Mario & Luigi: Dream Team
After freeing Boss Brickle in Mushrise Park by increasing the water pressure on the fountain that he is stuck in, the top part of the fountain will launch into the air, break a hole in the screen and get stuck in it before shattering the screen completely and falling onto Grobot, which results in him malfunctioning.

If the player goes to the menu after a long time, a notification advises players to 'take a break' after saving, like in Super Mario 3D Land.

Pi'illoper also breaks the fourth wall in-universe in his chronicles of the Pi'illos, by directly talking to Mario and Luigi.

One of the signs in Mushrise Park tells the player to look at the touch screen if they get lost. It appears to have been written by the Mushrise Park staff (more specifically, Brickle himself due to the heavy Bronx accent seen on such a sign)

If Mario and Luigi drink from the fountain on Mount Pajamaja, they will go into a dream, and "Game Over" will appear on the screen during the dream. Shortly after, Prince Dreambert wakes them up.

Mario & Luigi: Paper Jam
After Nabbit has stolen Bros. Attacks, Toad laments that, if Bros. Attacks were lost, it is over for not only for Toad himself, but also for Mario and Luigi, for Mushroom Kingdom, and the game itself. He then says that it's going to be Game Over for "for all of us".

At one point, Starlow breaks the fourth wall by looking at the player and saying "Now, back to the adventure!" (referencing Stuffwell's catchphrase from Partners in Time).

When Luigi is separated from Mario and Paper Mario, Starlow references the Year of Luigi to cheer Luigi up, and saying "It's basically Luigi RPG now!".

While the trio climbs the Paper Toad staircase to Neo Bowser Castle, along with compliments like, "You can do it!"' or tips like "Eat a healthy breakfast!" (which is a minor fourth wall break), another Paper Toad says "Make sure you save your game frequently".

Just like in the previous installment, the game tells the player to take a break if he/she goes to the menu after playing for a long period of time.

When Paper Mario gets an Excellent! on a Jump attack, he'll get a thumbs up to the player.

Mario vs. Donkey Kong
At the end of Credits 1 and Credits 2, Mario will say "Thanks very much for-to playing my game!", a line similar to the one at the end of Super Mario 64. Also, Mario makes several remarks at the credits in Credits 2 as they pop up (such as "Oh, the engineering! Mamamia!" and "Ooh, don't forget to thank Mr. Miyamoto."). Also, Mario breaks the fourth wall in every level (bar the Mini Mario and boss levels) by smashing the Mini Mario crystal ball against the screen to break it.

Mario vs. Donkey Kong 2: March of the Minis
When the player closes/opens the Nintendo DS, Mario can be heard talking, sometimes to the player such as "What's up?". Also, in the final cutscene, Mario, Donkey Kong, Pauline and the Toads are seen waving at the player.

Mario vs. Donkey Kong: Minis March Again!
When closing the DSi, Mario will either say "I love this game!" or "Hey! You get back here!" Opening it again will result in him saying things such as "Let's play again!"

Mario vs. Donkey Kong: Mini-Land Mayhem!
When closing the DS, Mario will say the same things he did in the previous game, along with some new ones, including "Ow, my head!" and "Whatta' you doing?"

Super Smash Bros. series


When a character is KO'd by being sent off the top blast line, they may occasionally hit the screen before falling and losing one of their stocks. This is called a screen KO.

Super Smash Bros. Brawl
When Mr. Resetti is released from an Assist Trophy, he may tell the players to stop resetting, as he considers it to be a form of cheating in the Animal Crossing games. Additionally, if the game is being played late at night, he may tell the player to "get some shut-eye".

When using Solid Snake's codec on Sonic the Hedgehog on Shadow Moses Island, Otacon says that people are excited that he is in Super Smash Bros. Brawl. In the codec on Mario, Colonel says that Mario made his first appearance in 1981, and in Jigglypuff's codec, he says that it takes all kinds of energy in Super Smash Bros. Brawl; Colonel also mentions the WarioWare games in Wario's codec. In Pit's codec, Colonel says that Pit has gone through "countless trials over the years", to which Snake replies, "And by 'trials', you mean 'Game Overs'?" Finally, when Snake uses his codec on Mr. Game & Watch, Otacon will talk about his first appearance, 1980, and his console, Game & Watch. There are other Codec Conversations that break the fourth wall as well.

There is a scene in the Subspace Emissary mode where Snake reveals himself after being hidden in his cardboard box for a long time. While facing towards the screen, he says "Kept you waiting, huh?" There are no other characters in his vicinity during the scene, so he must have been talking to the player - in reference to the fact that a brief scene of him hidden in the cardboard box was shown much earlier in the Subspace Emissary storyline. This is the only time the characters say a full sentence, excluding Pokémon.

In a similar manner, before facing Wolf O'Donnell in the Subspace Emissary, Wolf will appear to look at the screen, and strikes a pose at the challenger. Since Wolf doesn't interact with anyone directly, this is likely a sign of breaking the fourth wall.

During gameplay, super heavy characters, such as Bowser, will shake the screen when they hit the ground after jumping, due to their high weight.

Super Smash Bros. for Nintendo 3DS / Wii U
Bowser Jr.'s Final Smash, Shadow Mario Paint, involves painting a giant "X" across the screen itself.

In Duck Hunt's reveal trailer, the dog and the duck actually dodge their introduction statement.

In the Palutena's Guidance conversation for Link, Pit mentions how both of them were "born around the same time". Palutena also mentions the same thing during Pac-Man's conversation.

Luigi's Mansion
Melody Pianissima plays songs from the earlier Mario games and asks Luigi what game it appeared in. (Super Mario Bros. 3, Super Mario World, etc.). She will also play the Luigi's Mansion theme while Luigi is in the hallway next to the vase with the picture above it. Luigi occasionally hums and whistles the theme as well.

Whenever Luigi gets a key/valuable item, he shows it to the player.

An earlier version of the game shows Luigi looking at the player in the Foyer.

Luigi's Mansion: Dark Moon
Luigi hums the background music to the various mansions when the player doesn't touch the controls for five seconds.

Super Princess Peach
During the intro sequence, Bowser will tell the player to shut the door, using the Nintendo DS stylus, so that he and his minions could continue discussing their plan.

During the ending sequence, the player is asked, "So, how did YOU feel about this last adventure?" The player is also told that the Vibe Scepter might be in their house somewhere.

Mario Strikers Charged
Sometimes, the team captains will look at the screen, making it seem that they're looking at the player. One example is during one of Waluigi's losing animations where he looks at the screen and then prepares to punch it.

During Wario's home entrance, he will hum to his own theme.

Super Mario RPG: Legend of the Seven Stars
After Mario and Mallow join Geno while he's fighting Bowyer, Bowyer will retort that a three-on-one fight isn't fair. To compensate for this, the Y, X, and A buttons of the SNES controller will appear in front of him. Bowyer will then fire an Aero at one of the buttons, which will effectively lock the ability to use that button's commands (magic, items, or attacks).

Also, at the end of the game, the Mario Bros. and Princess Toadstool wave to the player and congratulate them for the completion of the game, and Princess Peach even thanks the player individually for helping her.

Television Series
Before many of the games listed above came out, the Fourth Wall was broken in several of the cartoon episodes.

Throughout the three DiC cartoons, commercial bumpers for the shows were announced to the audience by various characters at the start and end of the commercial breaks (i.e. "Be right back, paesanos!", "And now back to The Super Mario Bros. Super Show!"). These commercial bumpers can be viewed on the DVD sets of The Super Mario Bros. Super Show!, but were not included on The Adventures of Super Mario Bros. 3 DVD set. Additionally, the first three weeks of episodes for The Super Mario Bros. Super Show all contained unique bumpers featuring scenes and voice overs related to the episode's live-action segment. All of the later episodes used a few generic bumpers that were announced by Mario, and showcased a still shot from the opening sequence.

When The Adventures of Super Mario Bros. 3 aired on NBC during its original run, a character from each of the two upcoming episodes, as well as a character from Captain N: The Game Master, which aired between the two episodes, would all narrate a preview of the upcoming episodes before the show started. This trend continued with Super Mario World. These previews were not included on the DVDs due to the fact that they are considered the property of NBC.

The Super Mario Bros. Super Show!
At the start of the opening sequence, Mario shouts out to the audience "Hey, paisanos! It's The Super Mario Bros. Super Show!". In the live-action segments that aired from Monday through Thursday, Mario, Luigi, and/or the guest star will tell the audience to watch a preview of Friday's The Legend of Zelda episode. At the end of every episode, Mario, Luigi, and sometimes the guest star will say to the audience "Til next time, everyone... Do the Mario!"

Super Mario-Kun frequently breaks the fourth wall usually by heads-up display placement. For instance, in story arcs related to Super Mario 64, Mario's health displays often, at low health. In several instances during the arc based on Mario & Luigi: Bowser's Inside Story, the Nintendo DS Lite occasionally illustrates two simultaneous events, mimicking the game. A recurring theme within Super Mario-Kun is the preview for the future volume; a character partially "rolls" the page in the future volume, covering some of it.

Some dialogue within the Super Mario-Kun also breaks the fourth wall when trying to explain the plot. In one instance, when Mario questions Stuffwell why a someone is holding a Cobalt Star shard, Stuffwell dismisses it by saying that it happens regularly in the games.
