Well, not really siblings. Frankie is racing with his half brother D'Artagnan. They have the same father who I guess is a little slutty but have different mothers. If he didn't leap straight into the air before he started to run Frankie would be a bit faster but if he were human he would have been the odd kid who wore a cape every day in middle school. He has a flair for the dramatic which he definitely gets from his mother.
