MegaRyan104 on DeviantArt, you should check out his stuff.
I reviewed the first one a while back, and this character really deserves to be remembered more than he is. This is also some of MegaRyan104's art.
I reviewed the first one, that, like Vectorman, deserves to be remembered far more than it is. There was a remake of it recently, but it was a digital only game and I hate not having a hard copy so I haven't played it. Still, with swordplay and a jet pack, this character would be a blast to fight as. And the world just needs more Sparkster.
Wario Blast. Come on Nintendo, if anything he should have been in there before Pac Man.
So there you have it, my top 5 non Nintendo character who should be in Smash. Don't agree? Well then, make your own damn list.
