Exo-Skull is a humanoid grey rhinoceros with orange glowing eyes, dark grey fingers and toes, and red and black nearly impenetrable armor.
In Omniverse, his horn is recolored grey, his amour no longer has thick stripes, his arms and feet are covered by armor and have gained white bands, his head has changed shape, his amour does not cover his neck and part of his shoulders anymore, he has gained bolts on his elbows and upper legs, his ears are thinner and the front part of his armor has become blue with thin stripes. His toes are pointier, the bolts are now silver and resemble a fathead screw with a black light in the crease.
Exo-Skull seems to be surprisingly intelligent, even though he likes to skip the fancy stuff and focus on smashing things.
Exo-Skull respects his girlfriend, Subdora's need for artistic expression and is really supportive with her. However, when she was constantly failing to get the Orb of Pooma Poonkoo, he took over control of the operation.
In Fight at the Museum, Exo-Skull and Subdora are hired to steal a valuable artifact for Maltruant. Exo-Skull gives Subdora two chances to steal the artifact through her "artistic" methods. However, after she was thwarted a second time by Ben Tennyson and his associates, Exo-Skull insisted on doing things his way. He launched a devastating attack on the museum where the artifact was stored, and continued to pose a threat despite being immobilized by Gravattack. Eventually, he and Subdora escape with their prize and met with Maltruant to deliver it.
In It's a Mad, Mad, Mad Ben World: Part 1, Exo-Skull and Subdora rob an emporium and are confronted by Ben and Ben 23. Though they manage to escape, the Bens follow them to the warehouse where Maltruant is hiding. During their second battle, Maltruant's Chrono cog is activated, and they are all transported to Mad Ben's dimension. A short while after, they battle with the Bens once more over Maltruant's key. Both Exo-Skull and Subdora are defeated by the Clockwork/Techno-Bubble combination but are pulled away by Maltruant after he is reunited with his key.
In The Secret of Dos Santos, he follows Ben, Rook, and Kai as they enter the Temple of the Sky. After the trio discovers Maltruant's mainspring, Exo-Skull attacks them. He is defeated, but both he and the mainspring are pulled away by Maltruant.
In The End of an Era, he infiltrates Plumber Headquarters and steals the dwarf star from Argit, using its power to demolish his Techadons. When the present-day Ben and Rook are brought in to help, Whampire manages to defeat Exo-Skull by ramming into him with a Diamondhead-based helmet.
He and Subdora are ultimately abandoned by Maltruant as he travels back to the beginning of the universe, and are most likely taken into custody.
Powers and Abilities

Exo-Skull can shoot energy blasts and nets out of his horn.
Exo-Skull is immune to lasers.
Exo-Skull has two jet boosters attached to his back which allows him to fly.
Exo-Skull temporarily had access to the Dwarf Star, which amplified his natural strength.
Despite his durability, when Subdora was under Whampire's control, her teeth and claws were strong enough to rip and scratch Exo-Skull's armor, causing him great discomfort.
