If we're including Brawl, me. Pikachu is the cheapest character in the game. Trust me. Use his down-B constantly (if not that, charge your side-B or your down-A) and everyone is dead. But if we're talking about final smashes in the game, Sonic. His final smash is the cheapest and strongest.

Overall though, I don't really like Pokemon, so I'd say Sonic.
