Birdo
Birdo is a character in the Mario series. She first appeared in Doki Doki Panic, a Japanese game featuring Birdo as the first boss. After it's release in Japan, Nintendo of America remade it, featuring Mario characters, but kept the enemies and bosses the same. This remake was known to be Super Mario Bros. 2.
Birdo later appeared in many Mario spin-offs like Mario Tennis and Mario Golf as well as Mario Kart: Double Dash. In these games, he was known to be Yoshi's friend. There are several rumors regarding Birdo and Yoshi having a friendship. There have also been rumors that more than said activity had or is occurring, but it is unconfirmed. Birdo is also friends with the Shy Guys.
Appearances
For the SNES, Birdo appeared in Super Mario All-Stars as a boss, Wario's Woods as Toad's helper, and Super Mario RPG as a boss.
For the N64, Birdo was in Mario Tennis as Yoshi's partner, and Mario Golf as Yoshi's partner again.
Birdo appeared in Super Smash Bros. Melee for the GameCube as a cameo, Mario Superstar Baseball and Super Mario Strikers as Yoshi's teammate, Mario Kart: Double Dash!! as Yoshi's partner, and Mario Party 7 as an unlockable character. Birdo can be unlocked in the game by purchasing her in the Duty-Free Shop.
For the Wii, Birdo was in Mario Party 8, Mario Strikers Charged as Yoshi's teammate, Mario Kart Wii as an unlockable character, and Mario Super Sluggers.
In The Super Mario Bros. Super Show, King Koopa's main weapon usually has Birdo as part of its name.
Gender
The game manual for Super Mario Bros. 2 refers to Birdo as being male, and only thinking he is female.
Birdo's gender has been fluctuated over time. According to the North American instruction manual of Super Mario Bros. 2: "Birdo thinks he is a girl and likes to be called Birdetta.". Later versions of Super Mario Bros. 2 make no mention in either the manual or the video game itself. In Super Smash Bros. Brawl, Birdo's trophy description describes the character as "gender indeterminate," and uses the pronoun "it" rather than gender-specific pronouns such as "he" or "she". However, several other sources (see below) refer to her as a girl. The confusion surrounding Birdo's gender has also been addressed in a light-hearted matter, such as when Popple pauses before settling on calling Birdo a "dame" in Mario & Luigi: Superstar Saga. In Super Mario Advance though, the Birdos in that game had female voices. Currently, it is strongly implied that Birdo is female, but it has not been officiailly confirmed yet.
