"I didn't know you needed permission?"
The sheet states it needs permission on it. TWICE. Either you're pretty blind or just plain lying.

"I thought If I just gived credi-"
Not good enough.

"I'm sorry, really sorry, I'll remove them ASAP

Plus, it IS a wip, I needed to change the colors of the gloves and do some color work on the gloves, etc."
Great.

"Plus, you could AT LEAST be thankfull I gave you credit, and alot of it, I know a few people that have used your sprites that haven't even given credit AT ALL. They claimed it ALL with minor edits as their own work. But they deleted them at the last second so that the mods didn't kill them"
Stop pulling other people into this. This is about your problem right now. Not anyone elses. I will deal with anyone I see doing that myself.

"Once again, apologies, I will remove them. I'm just not as good of a spriter as you yet, needed Dark Sonic sprites, and thought that your work was the best by far that I've seen."
Stop ass-kissing. It gets you nowhere.
