I'm surprised this character wasn't flagged for plagiarism; the Overview page of this submission is ripped from Icezer's Super Sonic mod, and the CSS even uses the same text and artwork. It makes no attempt to have an identity of its own.
The character as a whole is very underwhelming and is something you'd see out of an early 2.1 Character. It's literally just a Super Sonic with a multicolour skin, some sparkles and weaker thok that can Armageddon Blast; he can't even breathe underwater or do the Directional Dash.
I can't really think of any positive notes to say. I suppose the Hyper skincolour looks nice, but that's all I can really think of, unfortunately.
This has serious potential, it really does, and I can see this becoming a fun character to play as with the right updates, additions and tweaks, but unfortunately with the way it currently is, it's just not worth playing as it doesn't bring anything new to the table.
