Fox is just a downgraded version of Wolf, who is very strong, but his smash attacks arent his strongest moves to send a person flying. But Once Wolf is unlocked, which you can do easily in the SSE (Subspace Emissary) You can unlock Wolf in the Ruins Stage, where Sharp Crystal Walls appear. This is later in the SSE though. But others would be Captain Falcon as well. He is pretty good at fights. Not as strong as Ganondorf, but faster. One other person i can recommend, Snake. Once he's unlocked, i advise using him. since you can get your opponent to like 179+ Damage quick and not let them even let them touch the floor as well. Being cheap with Snake is a fun thing to do :P And yes, to others, I used Olimar, he's alright. i just hate looking at him. >_<
Yo.
