Birdo

Birdo is a pink member of the Birdo species. Previously a villain, she's joined the good guys' side and has remained so for the foreseeable future.

Super Mario RPG: Legend of the Seven Stars
Birdo's egg was in Nimbus Castle, her egg taken care of by a Beezo.

During their trip inside the Valentina-controlled castle, Mario and his gang discovered her egg. Inside, Birdo asked if they could play with her as she's lonely. Cracking the egg wide open, Birdo was born and introduced herself as she fought the group.

After being defeated, Birdo retreated back into her egg, gave the gang the key deeper inside the castle, and asked them not to forget her.

Birdo joined the 8 bits as one of its important members. She and the rest of the 8 bits promptly took over Subcon, which sparked the people of Subcon to ask Mario to help free them.

In 4-3, she shoots an egg that allows Mario and the gang the only path forwards in stopping Wart's invasion.

Awake, she was later seen in Shogun Studios' Big Sho' Theater, performing as the love interest between two street Paper Macho Koopa Troopas gangs. Mario was prompted to enter the stage when Birdo acted out a plea for help from someone fitting Mario's qualifications.
