Sunder, known widely as "Sunder the Retriever", is an alien bounty hunter who first appeared in Singlehanded.


In Alien Force and Ultimate Alien, Sunder was a hulking, humanoid alien, with grey skin. He wore a black, overall-like outfit with red trim. Sunder had long, white hair, and a scar on his left eye. His eyes were black with red pupils, and he had two slits for a nose. In addition to that, Sunder also had a black trim around his face.

In Omniverse, Sunder wears a metallic mask with two black indentions around both of his eyes, in place of his scar. Sunder's eyes are now red, with black pupils. He also has a red scar, in the shape of an "x" on both of his shoulders. Sunder continues to wear the black overall-like outfit, with the red trim, with a few modifications; he now wears spiked shoulder straps, and spiked wrist bands, with three metal straps around both of his upper legs.


Sunder is very serious about his job, but he doesn't like to be tricked and some people touching his axe. [1]


Alien Force

He was sent by Vilgax to pursue Ben and to try to remove the Omnitrix from Ben by using his energy axe to bring it to his master. The result inadvertently sent Ben to the Null Void, while Ben's left hand remained on Earth. Ben's hand gains its own accord and manages to escape from Sunder by knocking him out before leaving to find help.

When the hand was found by Julie, she brought it to Gwen and Kevin. They fought to keep Ben's left hand from falling into Sunder's clutches. When Kevin invented a machine that could bring Ben back, it was a success, except that Ben's left hand ended up in the Null Void. As Sunder charged toward the group, Kevin activated the machine once again and restored Ben's left hand to his body. However, it also sent Sunder to the Void, who was last seen trying to get his axe back from a giant Havok Beast and being surrounded by cheering Havok Beasts.

Ultimate Alien

Sunder returned in The Transmogrification of Eunice, where he was on a mission to retrieve the Unitrix, which had 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 was revealed that he was hired by Azmuth o bring Eunice back to him in exchange for being released from the Null Void. Ben convinced Azmuth to let Eunice have a normal life and be one of his assistants, as he always needed help tending to Primus. When Azmuth, Eunice, and Sunder left, Sunder asked Azmuth if he was still getting paid, despite his failure.


At some unspecified point, Sunder got a new mask from Mr. Baumann.[DJW 1]

Sunder returned in Have I Got a Deal for You, having reverted to his evil ways, and battled Shocksquatch in Undertown. As before, he was after Ben's Omnitrix, but was defeated.

During Special Delivery, he and several other villains try to get the Dwarf Star in Ben's possession, but was again defeated.

In Cough It Up, he wrecks Sock Vendor's shop in order to get a mysterious item that he has never seen. The Vendor is unaware and offers him socks. Sunder is just about to finish him but he finds a pair of soft socks that he later takes. Ball Weevil appears to fight Sunder but gets tied up in socks. Before he could finish Ben once and for all, Spanner appears and fights him. At the Black Hole, he tells Psyphon that he wants to know more about this weapon. Psyphon points out that he likes his new socks which makes Sunder embarrassed. At the end of the episode he was banned from Undertown.

In Universe vs. Tennyson, he was freed by Chadzmuth from his cell but was later recaptured by Ben.

Powers and Abilities

Sunder possesses enhanced strength, sufficient enough to hold his own against Ultimate Cannonbolt, Kevin, Gwen, and Eunice all at once. He was also strong enough to overpower and briefly knock out Ultimate Spidermonkey.

Sunder is durable enough to withstand Diamondhead's shards to the face at point-blank range, though it still causes him discomfort.

Sunder is an expert on rare artifacts, and anything one needs to know to get them.[DM 1]


Sunder's laser gun

Sunder has an axe which is able to send whatever it slices to a different dimension when it strikes something such as the Prototype Omnitrix, as he was able to send Ben (minus his Omnitrix hand) to the Null Void.[1]

Sunder uses a hoverboard for flight and transportation, and has many gadgets inside it.

Sunder possessed a powerful blaster-pistol that causes dizziness. Although he had obtained it on Galvan Prime,[2] he did not get it from Azmuth.[DM 2]


Sunder is very dependent on his weapons, seen when he was sent to the Null Void and faced a Havok Beast who had taken his energy axe from him, demanding it back.

Vulnerability to electricity

Sunder is vulnerable to electricity, as shown when Shocksquatch defeated to Sunder.

Naming and Translations

Language Name Origin
Dutch Splijter From splijten, to split
French Séparator From séparer, separate
Hungarian Baltazár From balta, axe and the name Balthazor
Polish Szukacz From szukać, to seek


Sunder is another word for "steal by any means necessary" which is a reference to his bounty hunting job.


  • Sunder works for anyone as long as he gets paid.[DM 1] For example, he has worked for Vilgax.[DM 3]
  • The reason Azmuth hired Sunder is because he specializes in retrieving unique objects. As the Unitrix could have transformed into any sapient creature in the galaxy, Azmuth needed someone resourceful and tough.[DM 4]
  • Sunder is based off several villains from Marvel Comics. His general design resembles Terrax whereas his glider is modeled after the Goblin Glider used by the Green Goblin and Hobgoblin.
