The BBTS has preorder listings for the new line of comic book character figures from Shocker Toys, including Madman, a Grendel, and a Grendel variant. At least from this gallery of photos, it seems the one, if not both, of the Grendels is Grendel Prime from Matt Wagner's excellent Grendel: War Child.
Speaking of, Wagner's Batman/Grendel featuring Hunter Rose is possibly my alltime favorite Batman story.
