Petery Piranha is an abnormally large mutant Piranha Plant with petals on his head all around his chin. His first appearance is in Super Mario Sunshine, and since then he has gained much popularity and has since become a regular boss in Mario titles, despite seemingly being destroyed after each encounter. He also consistently appears in sports games and spin-offs. Petey Piranha is thought to be a loyal follower of Bowser, but this is undetermined. It is quite likely that he is the ruler of his kind, as suggested by his Japanese name, Boss Pakkun, "Pakkun Flower" being the Japanese name for the Piranha Plant. He has multiple special powers that set him apart from normal Piranha Plants, including spitting Goop, flying, and attacking with vines.
Several other "Giant Piranha Plant" characters appear throughout the Mario series, many of which bear a resemblance to Petey, including the Mom Piranha from Mario & Luigi: Superstar Saga, the Dino Piranha and Fiery Dino Piranha from Super Mario Galaxy, and the Peewee Piranha from Super Mario Galaxy 2.
