You may not know this, but Marcel does indeed have a were form. In his initial imagining, he was a Werewolf. A Silent Strider in the WoD universe. He's a dangerous son of a bitch.
I was lucky enough to score this original art by Ron Spencer, who is known for his work in the World of Darkness/White Wolf/etc systems. It was a contributor perk for the W20 project on Kickstarter. It is an original work, done for me, of my character. You won't find this image anywhere else or in any book.
