Baby Bowser appears in Yoshi's Island: From the Beginning as a secondary antagonist, and serves as the game's penultimate boss. During the events of the game, he primarily assists his father in his battle against the Yoshis.
Baby Bowser first appears to capture Usura Yoshi after the latter defeats several of his minions. He took the dark Yoshi to a prison beneath his castle, where he interrogates him about why the Yoshis hate the Koopas. Usura gave him a blunt answer: the Koopas are tyrants and the ones responsible for the chaos inflicting Yoshi's Island.
When fought in the Koopa Castle, he attacks Yoshi by throwing bombs and various other items at him. After Yoshi defeats him, he flees to the roof and summons a giant Koopa Troopa to his side: Hookbill Koopa.
During the game's climax, Baby Bowser stands before the room of his father and hears him calling the Yoshis weaklings, and fought Yoshi after his father's speech. After being defeated once more by Yoshi, his father denotes him a weakling, and fights a weakened Yoshi and Usura Yoshi in a powered up state, throwing his son aside. While two Yoshis defeat Baby Bowser's father, he flees the castle. In the epilogue, after the castle is destroyed in their fight, Baby Bowser is shown to be the one responsible for rebuilding it.
