Mirror mirror on the wall, who's the ugliest one of all?

Just for fun,I've decided to have a little 'Ugly Contest' between my favorite ugly Teenage Mutant Ninja Turtle action figures.

You can vote on the poll at the left, which closes 2/8/13 at 12:01pm.

Now meet the contestants!

MUCKMAN:

Muckman is a pile of living garbage. He also vomits slime.
Odds of winning: 2:1

SCUMBUG:

Scumbug is a human/cockroach hybrid. Cockroaches are not only disgusting, but the word 'cock' is right there in their name! He's filthy and ugly and his mandibles clatter when you wiggle his head. Odds of winning: 2:1

PIZZAFACE:

Pizzaface may be a walking doughman ala Clayface, or he may merely be a filthy homicidal degenerate who has been entrusted with the task of preparing your dinner. Is that pizza sauce or blood?!?!
Odds of winning: 5:1

MUTAGEN MAN:

Mutagen Man is a walking container of puss, bile, slime and entrails propelled by rotting non-human appendages.
Odds of winning: 4:1

Wyrm is a mutant flatworm with bulging eyes, worms for fingers, a tentacle for a leg, and a thirst for blood!
Odds of winning: 6:1

BAXTER STOCKMAN:

Baxter Stockman is a fly/human hybrid with fly claws, wings, and mutated legs. He's also a ginger.
Odds of winning: 10:1

WINGNUT:

Wingnut is a inter-dimensional bat creature with an ugly bat-pate and a bulbous tongue that dangles like dead flesh from his toothy maw. He also likes to hang upside down and scream a lot.
Odds of winning: 12:1

There you have it - this group of ghouls is, as my father would say 'uglier than a hat full of ass holes.'

But who is the ugliest? It's up to you to vote and let us know!
