Mortimer Clyde is a vampire hunter and the hulking cousin of Glen. If Glen is the brains, Mort is the brawn of their blackmail operations.

Mort makes it clear that he doesn't appreciate his cousin's belittling jabs whenever he states the obvious. But he's good at following orders and he's an expert with melee weapons, particularly blunt objects.

He is invariably partnered with Glen when they go on hunting trips.
