Sunder

Sunder the Retriever is a bounty hunter that first appears in the episode Single-Handed.

Ben 10: Alien Force
He was sent by Vilgax to pursue Ben and to try to remove the Omnitrix from Ben using his energy axe to bring to his master. 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 but sending Sunder to the Void.

Ben 10: Ultimate Alien
Sunder returns in the first episode of Season 2, The Transmogrification of Eunice, where he is on a mission to retrieve the Unitrix, which has taken the form of a girl named Eunice. At first, Ben and his team thought Sunder wanted Eunice for himself, but at the end, it is revealed that Azmuth hired him to bring Eunice back to him in exchange for Sunder's release. Ben convinces Azmuth to let Eunice have a normal life and be one of his assistants as he always needs a helping hand tending Primus, as it needs some help and care. When Azmuth, Eunice, and Sunder leave, Sunder asks if he is still getting paid.

After two failed attempts on Ben's life, Sunder fights Ben on the Eiffel Tower, but is soundly defeated by Ultimate Swampfire and thrown off the tower.



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 has many gadgets inside his hover board, and possesses superhuman strength sufficient enough to hold his own against Ultimate Cannonbolt, Kevin, Gwen and Eunice all at once. It is not known whether these gadgets are used for combat or sells them for profit. He is also shown to be durable, able to withstand repeated injuries such as being able to withstand Diamondhead's shards at point blank to the face, though it still causes him discomfort.

In The Transmogrification of Eunice, he possess a powerful blaster-pistol which he reveals he obtained on Galvan Prime (and likely is of Galvan design given its power). Though not specifically stated, it is possible it was given to him by Azmuth to help him in his task of retrieving the Unitrix/Eunice (meaning it is possible that the weapon was designed or constructed by Azmuth himself, but its not likely as Azmuth doesn't make weapons, so it was likely given to him from someone else as confirmed by Dwayne McDuffie ).

Trivia

 * He's similar to Red X in Teen Tians status wise as he is only looking out for himself and is neither a villain or a hero as show that he was fiercely chasing Ben in Single-Handed but didn't want anything to do with Ben in his next episode. It was only because Ben and his team interfered that he fought them similar to how Red X fights the Titans only when they interfere with his work.
 * He's another villain Ben has not defeated on his own. The others are Albedo and Aggregor.
 * Every episode or video game Sunder appears in Spidermonkey appears in.
 * He resembles Terrax from Marvel Comics.
 * He uses a Glider just like Green Goblin and The Hobgoblin characters from Marvel Comics. Someone mentioned this on Dwayne McDuffie's website and he said it "wasn't ever intentional".
 * His name could be a reference to the term "tossed asunder" or to the word sunder' meaning to part, separate, or divide (it should be note that Ben's hand was seperated from his body by Sunder, meaning that Sunder's name could be references to this).
 * He appears to be the same, or similar, species to Ragnarok and the Vreedle Brothers.
 * Dwayne McDuffie confirmed that he had worked for Vilgax.
 * He is one of Ben's most powerful enemies considering the fact that he was able to hold his own against Ben, Gwen and Kevin in both their battles. He also beat two ultimates.
 * Ironically, Azmuth (who is one of Ben's allies) had to hire Sunder, whos is one of Ben's enemies.
 * Why Azmuth hired Sunder was due to certain circumstances since he knows very well Ben, Gwen, Kevin, or the Plumbers could do the job Azmuth designed but their are a police force and he has no authority over them. However it is likely that given his plan to de-activate the Unitrix/Eunice should it become active, Azmuth likely predicted that Ben (and by extension Gwen & Kevin) might object it (as he eventually did), hence his decision to hire Sunder.
 * Though he is a villain, he is willing to work for Azmuth (who is a good guy and a mentor to Ben), however due to his status as a bounty hunter, he is willing to work for anyone who pays him (be it an evil warlord like Vilgax or the heroic creator of the Omnitrix, Azmuth), thus this makes him a free agent. Sunder's willness to work for Azmuth may also be due to Azmuth's being responsible for freeing him from the Null Void. Doing a job for Azmuth may be his way of repaying him for freeing him (however despite being in Azmuth's debt, he still expects to be paid for his services).
 * It is said by Dwayne McDuffie he was hired by Azmuth because he specializes in retrieving unique objects, and the Unitrix could have transformed into *any* sapient creature in the galaxy. Azmuth needed someone resourceful, and tough. He is also considered the best.
 * Sunder is another word for "steal by any means necessary" which is a reference to his bounty hunting job.
 * He is voiced by Powers Boothe who is best known as Cy Tolliver on Deadwood and Vice-President Noah Daniels on 24.
 * He bears a slight resemblance to Vilgax and the Enforcer Alien.
