Ridley

Ridley is a high-ranking member of the Space Pirates, and one of the main villains in the Metroid series of video games. He is directly responsible for the murder of Samus Aran's mother and partially responsible for the death of her father. In several instances, Ridley appears as an upgraded cybernetic version of himself called Meta Ridley. In addition to the Metroid series, Ridley has made an appearance in all games in the Super Smash Bros. series (aside from Super Smash Bros. for Nintendo 3DS), as well as in Nintendo Land in animatronic form.

Super Smash Bros.
In Super Smash Bros., Ridley can occasionally be seen flying in the background of the Planet Zebes arena.

Super Smash Bros. Melee
Ridley also makes a brief appearance in the opening cinematic of Super Smash Bros. Melee, where he can be seen battling his archenemy, Samus Aran. A trophy of Ridley can also be obtained in this game.

Super Smash Bros. Brawl
In Super Smash Bros. Brawl, Ridley is fought twice in the Subspace Emissary.

The first time he is encountered, he is fought by Samus and Pikachu. As the two reach the exit to The Research Facility, where her Power Suit had been held, Ridley appears without warning and snatches up Samus. Roaring, he slams her into a wall and drags her along it. Pikachu comes to Samus's rescue, hitting the space dragon with a Thunder attack, after which the battle begins. Ridley fights similarly to Master Hand, using many brutal physical attacks. When he is defeated, he falls off the arena.

He later reappears as Meta Ridley, attacking a group including Captain Falcon, Captain Olimar, R.O.B., Samus Aran, Pikachu, Diddy Kong, and Donkey Kong as they try to escape the floating Isle of the Ancients before it is engulfed in subspace.

As this battle is fought while trying to escape an island, there is a set time limit of two minutes that the player has to defeat Meta Ridley, who is more difficult to beat than Ridley was. Additionally, there is the added difficulty of the battle taking place on top of Captain Falcon's ship, the Falcon Flyer, so it is possible for the player to fall off the edge and lose.

Meta Ridley uses some of the same attacks as Ridley did, such as scraping his tail across the top of the Flyer and firing fireballs, but also shows additional ones that involve grabbing the Falcon Flyer and lowering it down with his weight, sometimes even lowering it off of the screen. Fortunately, most of Meta Ridley's attacks can be avoided by jumping off the Falcon Flyer at the right time. Meta Ridley's fireballs can also be reflected right back at him.

If the player manages to defeat Meta Ridley, a cutscene is shown, and the Falcon Flyer escapes while the island is engulfed into subspace.

Both fights are reprised in The Great Maze with any characters that have been rescued throughout the Subspace Emissary. He is also fought in the Boss Battles game mode. There is no time limit when fighting Meta Ridley in either The Great Maze or in Boss Battles mode.

Super Smash Bros. for Wii U
In Super Smash Bros. for Wii U, Ridley is a stage hazard boss on the Pyrosphere stage. His physical appearance, like Samus's, is based on his appearance from Metroid: Other M. Once attacked enough by a player, Ridley allies with that player, and attacks the other players. He can also transform into Meta Ridley by absorbing enough energy. He can be defeated, and, as if he was a character, defeating him rewards the player with a K.O. point; he can be defeated by his own ally as well.

Super Smash Bros. Ultimate
In the upcoming Super Smash Bros. Ultimate, Ridley has been confirmed to become a playable character for the first time, announced during the E3 2018 Nintendo Direct. His appearance in this game seems to be based off of that in Super Metroid. His Final Smash involves him destroying Samus's Gunship.

In addition, he appears in the trailer "A Piercing Screech" which revealed his playable status in the game.

Nintendo Land
In Nintendo Land, an animatronic Ridley appears as a recurring antagonist in the Metroid Blast attraction. Ice Ridley, a version of Ridley unique to this game, also appears.

Trivia

 * Ridley appears in Nintendo Monopoly, in which he takes the place of Tennessee Avenue. He costs $180.
 * Ridley's trophies in Brawl and Melee both state that he is the head of the Space Pirates on Zebes. This is false however, with the real head being Mother Brain.
 * Due to the time limit that is given during the Meta Ridley battle, Trophy Stands will appear more frequently, especially on the easier skill levels.
 * Ridley's stock icon for Super Smash Bros. for Wii U uses his appearance from Super Smash Bros. Brawl, instead of his Metroid: Other M appearance.
 * Ridley's stock artwork in Super Smash Bros. Ultimate resembles Bowser's stock artwork from Super Smash Bros. for Nintendo 3DS / Wii U.
 * Ridley's splash screen introduction in his Super Smash Bros. Ultimate reveal trailer; "Ridley Hits the Big Time!", may be a reference to "Ridley is Too Big", an internet meme originating from arguments against Ridley being a playable character in the Super Smash Bros. series.
