Bobobo-bo Bo-bobo (2005)

Season 1: Episode 9

Finally reaching the top of C-Block Tower, our heroes face off against the windy Geha the Gale (even though Beauty's already been saved). But when Bo-bobo and Don Patch are blown away by the competition, a new challenger finally makes his presence known: Gasser, master of the "Fist of the Backwind" and the boy that has been watching Beauty all this time! (though his appearance doesn't explain why Bo-bobo turns into a leopard)
