All right, I'll state this sensibly.
Fine, so the shoes and spike numbers are different. Fine, in your head, he has a different attitude, and abilities. But it's not possible to implement these into SRB2. The best you will be able to make is a Sonic equivalent, and that's what's bothering me. We have no need for Sonic equivalents. There is already a Sonic character. I mean, It's not about having a character that thoks. There's no problem with that. Or a character that can Thok and has the same basic abilities as Sonic. It's the fact that:
A) We already have two hedgehog characters with the same exact abilities.
B) To add another non-official character to the list that looks VERY similar to one we already have is pointless.
Again: It's possible to make sprite edits, as long as they're significant changes. And more than a shirt, and longer spikes. I mean, Shadow and Amy were done excellently. A mighty character is in the works, and I can say that it is nice. Why can these be done? Because they're more than a small altercation. They are real edits, with a lot of work put into them. Not a simple spike extending and shirt. And they are official SEGA characters, which is always a good thing. I'm not saying you SHOULDN'T make a Sonic-similar character, but you should really make it from scratch. Or at least use the minimum from the current sprites. Not small edits.
