Mega Mario

Mega Mario is a form that Mario and some others can become by eating a Mega Mushroom or simply Super Mushrooms in many games. This form allows the player to greatly increase in size, allowing them to defeat every enemy in his path and break almost anything (including Flagpoles).

Super Mario 64 DS
In Super Mario 64 DS, the Super Mushroom has the same effects as the Mega Mushroom, and makes the player into a larger size. The player can then obliterate almost anything in his or her path. The Super Mushrooms are always found in Bricks scattered throughout the level and are introduced in Bob-Omb Battlefield. The player however, cannot do any special types of jumps, such as the Triple Jump. If the player breaks more than 8 objects, he or she will get a 1-up for every extra object he/she destroys.

New Super Mario Bros.
The Mega Mario form returns in New Super Mario Bros., and is very useful sometimes. The more objects Mega Mario breaks, the bar above his head will get filled in. If he crushes a certain amount of objects, Mega Mario can gain up to five 1-Up Mushrooms. Mega Mario also has the ability to squash any of New Super Mario Bros.' bosses in one hit, including Bowser in any of his forms. When Mega Mario falls into the purple toxic water or lava, he immediately shrinks back to Super Mario and gets defeated. Also, if he become Mega Mario in tight spaces, he will return to his original form and the Mega Mushroom will return to the touch screen in the reserve item slot.

Mario Party 3
In the mini-game Toadstool Titan, characters could obtain the mega form from taking a Mushroom hidden in one of the Brick Blocks. Once the character had obtained the mushroom, he or she was capable of knocking out other characters in a short period of time. Mega characters could not jump and control their moves, however.

Mario Party 4
In this game, the Mega Mushroom cause one to enlarge in size and hit two Dice Blocks. While Mega, the player can take 10 coins from any opponent the player squishes. The Super Mega Mushroom works the same way, but with three Dice Blocks.

Super Smash Bros. series
In Super Smash Bros. Melee and Super Smash Bros. Brawl, any character can become Mega by acquiring a Super Mushroom. When a player is Mega, his or her attack power increases by a fair bit and launch resistance increases. However, it makes the character easier to hit and pelt them with attacks. In Super Smash Bros. Brawl, the final event match pits the player against Mega Mario, Snake, and Sonic. Both games also offer an option to play as Mega for an entire match.

Paper Mario: The Thousand-Year Door
In Paper Mario: The Thousand-Year Door, Mario or his partners can become huge by using a Power Punch. This increases their attack power briefly for a few turns. Also during a few Bowser intermissions, if you eat enough meat it has the same effect as a Mega Mushroom and makes Bowser invincible and huge for a brief time.

Super Paper Mario
In Super Paper Mario, when Mario (or Luigi, Princess Peach, or Bowser) grabs a Mega Star, he/she will turn 8-bit, much like his/her sprite from Super Mario Bros and grow to giant proportions as well. As Mega Mario, Mario will be able to break blocks, enemies and anything in his path, much like the Mega Form from New Super Mario Bros.

Mario Super Sluggers
In Mario Super Sluggers, any character can become temporarily Mega by finding a Mushroom in the mini-game, Graffiti Runner. When a player is giant, he or she can create small earthquakes that can paralyze all ground opponents for a brief period. However, he/she is still vulnerable to body checks, Chain Chomps, and characters that have a star in effect.

Mario Kart Wii
In this game, the Mega Mushroom appears as an item. When the character utilizes the Mega Mushroom, the he or she becomes gigantic, allowing him or her to squish opponents and get a speed boost. However, the player is not immune to Thunderbolts, invincible racers or Bullet Bills.

Trivia

 * According to The InterNed, the music in Super Paper Mario that plays while Mario or another character (including a Koopa) is in Mega form is titled "An Unrivaled Battle."
 * A similar form to Mega Mario, though unnamed, appeared in the Club Nintendo comic "Mario in Mariozilla". Kamek accidentally turned him into this state.
 * In Super Mario 64 DS, the only time when Yoshi can punch is while he is in his Mega state.


 * Originaly in "New Super Mario Bros" if a "Goomba" touched the "Mega Mushroom" he would turn into a Mega Goomba. They later putted it out of the game cuz the game would be even harder.
