Sunder

Sunder is a bounty hunter that first appears in the episode Single-Handed. He is voiced by Powers Boothe.

History
He and Sevenseven pursue Ben and try to remove the Omnitrix from Ben using his energy axe. The result inadvertently sent Ben to the Null Void, but left only Ben's left hand on Earth.

When the hand is found by Julie, she brings it to Gwen and Kevin. They fight to keep Ben's left hand from falling into Sunder's clutches. When Kevin invented a machine to bring Ben back, it was a success except that Ben's left hand is now in the Null Void. As Sunder charges toward the group, Kevin activates the machine again and restores Ben's left hand to his body. Sunder was sent into the Null Void with his master Vilgax slicing his waist with his energy axe. He was last seen eaten by an alien creature.

Powers and Abilities
He has an axe which is able slice through things. It can also send whatever it slices to a different dimension, as he was able to send Ben (minus his omnitrix hand) to the null void. He also uses a Hover Board for transportation. He is also strong and has many gadgets inside his hover board. It is not known whether these gadgets are used for combat or sells them for profit.
