Varolz the Scar-Striped is a massive troll who is a member of the Golgari. He's who the Golgari call upon when there is real danger. Varolz has a symbiotic fungi living on him that repairs his wounds, replacing his skin with tough scar tissue which means that the more battles he's in, the tougher he gets. He has a wicked looking knife and some totemic Golgari charms on him. Varolz is about 12-15 feet tall.
The Golgari maze-runner Varolz hungers to prove his fortitude in battle, and his trail of victims feeds other hungers. (Crypt Incursion)
