This is Hercules, A giant male Raichu that was Cocoas first love. They both were pokemon in a stunt circus together, they were happy for a while but when Cocoa started training and began to win too many pokemon battles he felt she was eclipsing his fame and the ensuing rows made them split up. He is a very powerful fighter and has a fearsome temper and he vows one day to try and win Cocoa back.
