Petey Piranha (Japanese: ボスパックン Bosu Pakkun) is a large Piranha Plant and a recurring antagonist in the Super Mario series. Petey Piranha first debuted in Super Mario Sunshine as the boss of Bianco Hills, where he seemingly lives. Petey's drastically different appearance compared to normal Piranha Plants is due to a mutation, though he still shares many traits with his pipe-bound brethren such as being lazy and often depicted sleeping or being ravenous omnivores. Petey is also often depicted to be of limited intelligence, rarely speaking intelligible language outside of Paper Mario: Sticker Star, and is also fairly clumsy due to his large size; Petey also possesses a fair sense of humour, and will also acknowledge his faults with comical movements such as him slapping his own face. One of Petey's most prominent skills is the ability to create an apparently-endless supply of Goop, which he shoots out of his mouth. Petey Piranha is seemingly the leader of the entire Piranha Plant species, with several in-game biographies and his Japanese name implying such. Petey is also shown to be friends with King Boo; this is likely a reference to how their two debut titles were released on the Nintendo GameCube (Super Mario Sunshine and Luigi's Mansion, respectively) and focused primarily on one of the two Mario Bros. (Mario is the main protagonist of Sunshine while Luigi is the main protagonist of Luigi's Mansion).
Similarly to Birdo, Petey Piranha's gender is a matter of debate among fans of the Super Mario series. Petey is commonly referred to as being either male or genderless in English and Italian media, though this is not true for the rest of the world. In French media Petey Piranha is referred to as a female and goes by the name of "Flora Piranha"; many other languages are inconsistent about Petey's pronouns, with German media referring to Petey as a male in Super Smash Bros. Brawl but as a female in Mario Strikers Charged, and most Spanish language titles aside from New Play Control: Mario Power Tennis, where Petey is referred to as female. In the Japanese-exclusive Super Mario-Kun comic, Petey Piranha is depicted as the mother of several Piranha Plants.
