This Figuretoon was "written" (unknowingly) by one of our readers, Monty Prime, on Twitter.
Darkmount, as we explained in this review, is the name of Straxus's big evil fortress. And according to TF Wiki, Straxus's trademark quote is "Mercy is not dispensed here, fools... only death!" Since the Straxus/Darkmount figure is such a vibrant blue, we darkened him up for this Figuretoon - being nearly black suits him.
The background - our version of Fortress Darkmount - is a screenshot from some videogame no one's ever heard of. And you may have noticed that those trick-or-treaters are the same ones that Poe took out several years ago. Those poor kids just can't catch a break!
