So I just caught up with the thread now. All I can really gather is that Sakurai is ageless. And that he could very well be some sort of Vampire King. He will unleash 10,000 years of darkness, with Brawl Ganondorf.
Also Dillon is pretty cool. If we did have more newer characters, I would very much look forward to his inclusion. As for being a Sonic clone, I feel he can stray away well enough from the blue blur. Unlike Sonic, he can burrow undergound for some attacks. He uses various types of crystals in his games. Like the freezing crystal. And he does chuck Dynamite. Instead of punching, he could use his claws for slashing, mix in some kicks as well.
