How do you get Groudon on super smash brothers brawl

you cant really get groudon on ssbb well you cant be him as a character in the game.you can evantully find him in a pokeball if you want to try to find him go on training mode and keep on adding pokeballs until groudon comes out.you can also get the trophy of groudon.if mew celebi or jirachi come out they will leave rare music disc and trophies behind(not in training mode).hope this helped.
