Young Nasty Man 

Rival and Arch-Nemesis of Wonderboy, with powers comparable to Wonderboy's! They later join forces to create the greatest band the world has ever seen, Tenacious D. Has the power of flight, and can kill a Yak from over 200 yards away...with mind bullets!

Wonderboy and Young Nasty Man killed the Hydra by slicing it's throat, and grabbing its scroat.

Crusty NastyAnus 

The remainder of goop left over from a massive shit that plopped into the toilet, causing the poo, pee, vomit, bacteria, menstrual blood, and whatever else is in your toilet at the time to spew up into your anus, leaving you with a dripping mixture of FUN.

Sam:Yesterday I let go of a perfect 'S'!

Joe: AWESOME!

Sam: Not really... left me with one hell of a Crusty NastyAnus
