Well, Wonderboy and Young Nastyman joined forces;

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.
