Coming staight from the Adult Swim show Metalocalypse is Nathan Explosion. Nathan is Lead singer for the band Dethklok and can really growl. The shows so popular that a Dethklok CD has been released along with Seaon 1 of the show. As much as I hate to say this for a "fake band" Dethklok has some of the best metal sounds I've heard in a long time.
Nathan was originally a training gear Rocky (I got him for Batous jacket). I used a mix of Psylocke, Mrs Fantastic 12", and sculpt to do the hair on a TNA Rhino head. I repainted the pants navy blue and then created him a mic. I used an actual CD for the base and added the Metalocalypse and Dethklok logo plus Nathans name.
Lawyer: Time Travel Face Bag, am I saying that right? Looks like you have some uh, plastic bags. What are you doing?
Nathan: We're travelling through time.
Toki: Yeah, you puts this face bag on and you travel through time!
Murderface: Dear God, you boy in the street, what day is it?!
Pickles: It's Wedns.. er it's Friday, it's Friday.
Murderface: I must have travelled through time itself.
Nathan: We've figured out how to travel through time, at the speed of regular time, with plastic bags.
