Atomisaur is the Biomnitrix's fusion of Vaxasaurian DNA and an unknown DNA sample from the planet Terradino and an unknown planet.

He is a fusion between Atomix and Humungousaur.


Atomisaur is easily identifiable as a fusion between Atomix and Humungousaur, possessing the most easily identifiable elements of both aliens. His overall body shape resembles that of Humungousaur, albeit made of white, green, and black metals. He has Atomix's energy cylinders inside his chest and arms, a long with the faux-omnitrix symbol in his chest. The Biomnitrix symbol appears on a belt around his waist.

Transformation Sequence

Extract from Chapter 5 of Death of Ben 10:

"The sound of two omnitrixes play as Ben immediately grows to 20 feet tall. His arms bulge with green cylinders, and his neck extends out. When the glow fades, a large white and green dinosaur stands. It is a fusion between Atomix and Humungousaur."

Powers and Abilities

Atomisaur's powers are a combination of those possessed by Atomix and Humungousaur.

Atomisaur is shown to be able to generate and manipulate nuclear energies through his hands, however unlike Atomix he does not name his attacks. These attacks can do high amounts of damage to whatever they touch with their strength varying by how much energy was put into them

He possesses incredible physical strength, far stronger than Atomix alone would be. He is also very highly durable.


Perhaps Atomisaur's only weaknesses are the powers that this fusion loses. He is unable to grow any taller, unable to fly, and he loses his enhanced speed. His control over his own atomic energy is not as precise as Atomix's.


Death of Ben 10

He is first used by Ben 10'000 in Chapter 5 to defeat Albedo, with a little help from his son Ken as Buzzshock. He is later used again while Ben 10'000 is hunting down Apollo through San Diego Ironworks in Chapter 14.
