Petey Piranha (ボスパックン, Boss Packun), is a recurring villain (usually a boss) in the Mario series.
Petey Piranha first appeared in Super Mario Sunshine as the boss for episodes 2 and 5 of Bianco Hills. In both battles, his main methods of attacks are spitting out large amounts of brown goop on Mario, and if the player gets close enough, hitting Mario with his head by spinning it around himself. In episode 5, he gains the ability to swing his arm to cause a tornado that sends Mario flying upward.
In Brawl, Petey Piranha's attack where he swings the cages he is holding is similar to his swinging motion in Super Mario Sunshine, except he does not cause a tornado. His stomping attack in Brawl is very similar to his attack in New Super Mario Bros..
While the cutscene prior to the first fight with him seemingly depicts him spitting out a cannonball at Mario, Petey Piranha has never had the ability to do so in the Mario series.
Petey Piranha appears as the first boss in Super Smash Bros. Brawl's The Subspace Emissary mode, holding the cages of both Peach and Zelda at the end of the Midair Stadium. The player, who is controlling Kirby, must destroy one of the cages to defeat Petey. The player can also attack Petey's head, which splits the damage received to both cages.
Once a cage's health is depleted, he will break and free the princess inside while Petey catches on fire, collapses, and explodes. If both cages' health is depleted simultaneously via an attack on Petey's head, the game will randomly decide which princess is freed. The unsaved princess will be turned into a trophy by Wario. At the last level, Tabuu resurrects Petey, along with the other bosses, and sends him after the heroes in The Great Maze.
Like all bosses, Petey can be fought outside of The Subspace Emissary in Boss Battles Mode. During this mode or in The Great Maze, Petey's cages will be empty and the sky in the arena will be blue (compared to in the Midair Stadium, where his cages will contain the two princesses and the sky will be an ominous red).
Petey has only two main attacks. The first involves swinging one of the two cages along the ground. The second is a jumping attack, where Petey tries to stomp the player while holding both cages vertically. Any contact with Petey or his cages during this attack will meteor smash the player as he comes down from a jump.
When either cage is reduced to 2/3 and then 1/3 health, Petey will roar and its body will glow momentarily, surrounded by a red aura. Petey will then speed up its attacks and often jump in a different pattern, usually two times in a row; his attacks will also deal slightly more damage and their knockback will be boosted. A cage hit after this roar gains One-hit KO power for the first hit only on Intense difficulty.
Like all bosses, Petey Piranha can be controlled with hacks in Boss Battles Mode. The start button will, like all bosses, self-destruct him. Unlike any other boss (besides of Meta Ridley), when controlled by a human, Petey Piranha will wait in a T-pose after either roaring or performing a cage attack.
HP and damage taken
The resistance values above apply only when hitting Petey's body, which will deal the resulting damage to each cage. When hitting an individual cage, no resistance modifier is applied. When either cage's HP is depleted, Petey is defeated.
Like all bosses in Brawl, Petey gains an additional ×0.6 damage resistance modifier when fought in co-op mode, effectively gaining 67% more health. This modifier is applied whenever the second player is in-game and is no longer applied if the second player loses all their stocks.
A colossal Piranha Plant. Unlike its pipe-inhabiting cousins, it uses its legs to walk around. It can fly, too. As you might expect, it often appears as a boss character in Mario's adventures. This may come as a surprise, but it also displays surprising dexterity in kart races and ball games.
Even more curiously, there are no leftover models, textures, sounds or parameters with which these animations would correspond, as only the animations appear to remain in the game. The lack of leftover assets would appear to imply that Petey Piranha was scrapped at a very early stage in development.
As a Final Smash

Cosmetically, Petey Piranha has a more saturated color scheme than he did in Brawl, and is more smoothly textured (i.e. no cracks in his skin as in the aforementioned title.)
Additionally, he is mentioned in the Palutena's Guidance for Piranha Plant, as well as Paper Petey Piranha and Petea Piranha.
