I've been meaning to get George back in the role of Zombie-man... I didn't know how I'd do it-- so I just did it.
For those new to ZR, Zombie-man is George's hero persona, he's been using it for a while to dispense zombie flavored justice to the city. Most recently he donned the cape and tights to fight the menace that was zombie Santa.
But he hasn't been Zombie-man for a while, since he wasn't a zombie... he's recently tried getting back into the swing of things.
George has only been able to kill people who have wronged or gravely annoyed him
... so a criminal fits that bill just fine.
