It all depends on your style of playing. Personally, the best character is, to me, Kirby (runners-up would be Marth, Lucario, and Link). The tier-list ranks him as very low, but anyone can turn a poor brawler into a master.
Sonic.
Kerby

There is no Roy in ssbb. Roy only makes an appearance in SSBB as a sticker .He's not a playable character.

Geno does not exist in SSBB. It is possible to texture hack to make a character look like Geno, but Geno is not a real character in SSBB.
He's not as a playable character in SSBB, but you can use him as a Assist Trophy.
