Birdo (キャサリン, Catherine) is a character from the Mario universe.
Birdo is a character and species in the Mario series who debuted in Yume Kōjō: Doki Doki Panic as a recurring boss at the end of several levels. In the game, Birdo attacks by spitting eggs at the player and is defeated by grabbing the flying eggs and throwing them back at it three times. Later worlds introduce differently colored Birdos which also attack with fireballs.
Like much of the content in Doki Doki Panic, Birdo was retained when the game was reworked for its North American release as Super Mario Bros. 2. Since then, Birdo has appeared in numerous Mario series games, being a boss once again in Super Mario RPG: Legend of the Seven Stars and Mario and Luigi: Superstar Saga, and a playable character in several installments of Mario spinoff series such as Mario Kart and Mario Party.
Birdo's gender is described as "indeterminate" in Brawl, referencing a long-standing debate in her home series. She was initially described as a male who "thinks he is a girl" in Super Mario Bros. 2's instruction booklet, suggesting that she is transgender. Most other game appearances refer to Birdo as female, but usually ignore her transgender identity as a whole. One mission in the 2008 Wii game Captain Rainbow is based on the gender debate, tasking the player with finding evidence that Birdo is female after she was arrested for using the women's restroom.
As a stage hazard
Birdo is a stage hazard in the Mushroom Kingdom II stage. She appears on either side of the screen and shoots one or three eggs from her mouth before exiting to the side where it came from. Birdo can be attacked and will temporarily retreat after receiving enough damage.
Birdo's eggs deal damage to those they hit. These eggs can be shielded against, jumped on, knocked away with attacks, and air grabbed. When air grabbed they are usable as items that deal 24% damage when thrown normally, explode and deal 49% when smash thrown, and occasionally drop items after breaking. It is the only item in the series that can explode by input rather than chance.
The Birdo trophy is obtained randomly: when this happens, Mushroom Kingdom II is unlocked. As with the stage, Birdo appears as her SNES sprite.
