AniHawk

AniHawk is a neat poster, but sometimes hard to get a handle on.  The thing is, he can make serious posts, and facetious posts.  Unlike a joke character, they're not always facetious.  Unlike most other posters, he doesn't tend to make it obvious through text or imagery when he's being facetious.  So he slips in and out, and even when you're used to him doing this it can be hard to tell how worthwhile it is to refute a point he's made, when he might not have even really meant it.

Almost always uses an avatar of Ramirez from Skies of Arcadia.  People get weirded out when he changes it.
