Once you have acted on the feedback given by a Reviewer on a rejected OC you can immediately put them back into the pending character category so they can get reviewed again, if all was fixed and matches the rules it should be accepted.

As for Hellhound, you can request a page deleted by adding it to the "Candidates for Deletion" category, then an admin can delete it. Since this is about a fanfiction villain i can't really give much advice without the context of your plotline or story themes, but i do have some general advice. Try to keep him a protagonist, at least in his own mind, and have all he does make perfect sense to him thanks to the backstory he underwent. If you keep his origin as being an alternate universe version of your protagonist don't have that be in name only, have the same core personality and values as the original, only taken too far.
