To defeat Tabuu you need Snake,(play Shadow Moses island 15 times)Lucario,(have a character complete all 5 taget tests)Falco,(complete 100-man Brawl)Sonic,(beat clasic mode with ten characters)Ganondorf'( clear clasic mode on hard with Link/Zelda)and Fox. Snake can shoot those missles,Lucario can hit harder than most characters,Falco is a cool close range character,Sonic can run very fast, (somtimes TOO fast)Ganondorf can probably hit harder than Lucario, and Fox can shoot very fast, but it gives little damage.
