Ridley is a space pterodactyl, the leader 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 four games in the Super Smash Bros. series, as well as in Nintendo Land in animatronic form.
Super Smash Bros. series
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.
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. Ridley is next fought in The Great Maze with any characters that have been rescued throughout the Subspace Emissary. He uses the same attacks and is defeated in the same fashion as before. Remixes of Ridley's theme music from various Metroid games can be optionally played in the Frigate Orpheon stage.
In Super Smash Bros. for Wii U, Ridley is a stage hazard boss on the Pyrosphere stage. His physical appearance, like Samus', 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 will reward the player with a K.O. point; he can be defeated by his own ally as well.
Ridley first appears in the seventh level of the Assault Mission mode, "Destroy 10 Cyclons". Unlike in its later appearances, the Ridley robot can't be defeated directly here, but it is possible to make it leave the arena by shooting all its weak spots multiple times. This gives no reward, however, and only makes the rest of the mission much easier as he will not disturb the player. Ridley later makes a proper appearance in the twentieth and final main level, "The Final Battle". Here, Ridley is fought in three stages, in each of which the Mii players must destroy targets on its chest, mouth, and tail. In the first stage, Ridley attacks by firing beams from its mouth and shooting its tail. The second stage adds a target on its right hand, which detaches from its main body and attempt to attack the Miis, as well as firing missiles at the Miis. The final stage of the battle places one additional target on its left hand, which fires beams as well.
In the extra stages of Metroid Blast, Ice Ridley is introduced, but the normal Ridley makes another two appearances as well. In level twenty-eight, "Ridley and Ice Ridley", the Miis must fight both forms of Ridley at the same time, as implied by the title. Ridley appears for the final time in level thirty, "The True Final Battle". As with its first appearance, Ridley cannot be defeated; it is merely a distraction for fighting the level's actual opponent, Kraid.
