Pretty much this, yeah. The Rouge sprites aren't actually representing Rouge but random characters. The Blaze and Big sprites are used because they are cats, and not because they are Blaze and Big. And Metal Knuckles, while named as such, isn't even really a character in his one game appearance, so the version here is largely an original creation. (And Metal Knuckles was added after the blog was originally deleted, I believe.)

There's the other issue about this basically being a sockpuppet account too, although since we all know it's OMG maybe that's not such an issue?
