Well, when you have it paused and you're moving the camera around, the shine looks really good.
As for Genosect, I keep looking at him, and realizing how complicated he is, but maybe. He could go into his UFO form whenever Samus goes into her ball maybe. Anyways I think Samus would be the best fit, what with her beams and all. Plus Samus has hardly any pokemon hacks (does she even have any?)
Also, I really like Sandslash a lot, and I think he'd be cool on Sonic. Though Carnage is adamant about him being on Bowser (for valid reasons, but I just think Sonic has more of a Sandslash feel). Flygon was going to make one on Metaknight, but i don't know where he is on that.
legs and arms lol that would be a problem
Legs shouldn't be a problem if it uses Sneasel/Classic Sonic's skeleton maybe. And for the arms, just don't rig past Sonic's elbows.
