Trumpenstein — Perhaps as simple as Frankenstein with yellow or orange hair, but the possibilities are endless!
The Great Trumpkin — Think of a ghoulish jack-o-lantern oozing orange-ish decomposing pumpkin pulp! Eeew!
Lurch — Similar to Trumpenstein, but perhaps with a silver serving tray, since Lurch was a butler.
The Grim Groper — Perhaps a Grim Reaper costume with "Trump touches" .
The Posh Wear Wolf and The Orange Hair Wolf — Perhaps a wolf man with orange hair, in a tuxedo or a black suit with a red tie.
The Orange Blob that ate Everything in Sight — The world is Trump's oyster, or perhaps his taco bowl! Trump also likes to snack on Oreos and wolf down junk food.
Lord Voldemort — Inspired by Rosie O'Donnell, so there is a revenge factor here!
Count Hackula — Trump has been very Twilight-ish during the debates, so let your imagination roam free!
The White Kanye ― Coined by Bill Maher, this one may require more thought.
The Short-Fingered Vulgarian — Coined by Graydon Carter (a nickname Trump hates because he seems to think it implies that he is under-endowed "down there").
Number one, with a bullet: THE ANTICHRIST — by God and the Hebrew prophets; when they spoke of "the Trump of Doom" and a "little horn" were they speaking literally?
