Atomic-X is the combination of Alien X and Atomix's DNA. He can only be accessed by using the Biomnitrix.


Atomic-X greatly bears the body similar to Alien X. His arms have large green cylinders filled with energy and orbs on his shoulders. His eyebrows take the shape of Alien X's horns. He has the basic characteristics of Atomix, including upper torso, collarbone, lower jaw, waist, thighs and feet as well as sharing the same height of Atomix.

Atomic-X wears the Biomnitrix on his chest.

Powers and Abilities[]

As a fusion, Atomic-X circumvents the need for Serena and Bellicus,[DJW 2] allowing Ben 10,000 to use a Celestialsapien's reality warping powers without debating.[DJW 1][note 1]

Atomic-X has an extremely high level of enhanced strength, capable of knocking Vilgax into the air with a mere flick of a finger.

Being part-Celestialsapien, Atomic-X can teleport anywhere he wishes.

Similar to Atomix, Atomic-X can shoot energy beams from his fists and is capable of flight.

Atomic-X can create multiple orbs that appear to be combinations of light fusions and black holes without physically doing anything.[1]


Atomic-X can be destroyed by a Chronosapien Time Bomb.[2]

Atomic-X is vulnerable to time attacks of a Chronosapien.[3]

Atomic-X is weaker than Alien X, as his DNA is diluted due to being a fusion.[DR 1]

Atomic-X's name is an indirect combination of Atomix and Alien X.


  • Unlike Atomix[DJW 3] and Alien X, Atomic-X has a mouth.
  • This is the only fusion in which the name does not just use parts of the aliens' names used as the basis for its composition, since neither Atomix nor Alien X have a "c" in their name.


  1. 1.0 1.1 There has been much debate between fans as to if Alien X (and Atomic-X by extension) is to be considered omnipotent or nigh-omnipotent. Derrick J. Wyatt has stated that Atomic-X has the same powers as Alien X,[DJW 1] while Duncan Rouleau stated that any fusion with Celestialsapien DNA is less powerful than Alien X due to the Celestialsapien DNA being diluted.[DR 1] Due to this and his aforementioned weaknesses, some fans consider him to be nigh-omnipotent. The discretion is left to the reader to decide which category to put Atomic-X in.
