No, no! Make it stop! I can't be all of them! Not all at once!

Ben right before turning into the mutation, Vilgax Attacks, Part 5.


Fusion Ben refers to an involuntary fusion of Ben Tennyson and his aliens in Ben 10 (Earth-RE15).

Powers and Abilities

First Fusion Ben

Fusion Ben possessed access to all the abilities of his original ten aliens, while also negating the majority of their weaknesses. Due to the rough combination of strength, he was physically stronger and more durable than a full-sized Humungousaur.

Fusion Ben demonstrated the following abilities:

  • Pesky Dust's flight and enhanced agility
  • Swampfire's enhanced strength, agility and durability, control of plants and regeneration
  • Chromastone's enhanced strength, agility and durability, energy beams and reflective body
  • Jetray's flight, enhanced agility and durability, and neuroshock beams
  • Humungousaur's enhanced strength and durability
  • Spidermonkey's additional limbs, enhanced strength and agility, and webbing
  • Brainstorm's electrical blasts and multiple legs
  • Big Chill's flight, ice breath and enhanced strength
  • Goop's metamorphic body and elasticity
  • Echo Echo's sonic screams and enhanced agility

Second Fusion Ben

Much like the original Fusion Ben, the second Fusion Ben possessed the abilities of the original ten aliens without their weaknesses. However, the second incarnation of the fusion was far superior to the first due to having the DNA of those aliens' Ultimate Forms included into his DNA, as well as the secondary set of aliens. Due to the rough combination of strength, he was physically stronger and more durable than a full-sized Ultimate Humungousaur.

Unlike the original fusion, the second Fusion Ben possessed Ben's intact mind, allowing him to fight alongside Gwen, Kai and Cooper.

Fusion Ben demonstrated the following abilities:

  • Pesky Dust's flight and enhanced agility
  • Swampfire's enhanced strength, agility and durability, control of plants and regeneration
  • Chromastone's enhanced strength, agility and durability, energy beams and reflective body
  • Jetray's flight, enhanced agility and durability, and neuroshock beams
  • Humungousaur's enhanced strength and durability
  • Spidermonkey's additional limbs, enhanced strength and agility, and webbing
  • Brainstorm's electrical blasts and multiple legs
  • Big Chill's flight, ice breath and enhanced strength
  • Goop's metamorphic body and elasticity
  • Echo Echo's sonic screams and enhanced agility
  • Ghostfreak's rotatable eyes, flight, intangibility, tentacles and sharp claws
  • Lodestar's magnetokinesis, telekinesis, enhanced strength and ferrokinesis
  • Rath's sharp teeth and claws and enhanced strength, durability, speed and agility
  • Gravattack's gravity manipulation, enhanced strength and durability, planetoid form and force field manipulation
  • Cannonbolt's rolling ball form, armoured shell and enhanced strength
  • Blitzwolfer's sonic screams, enhanced strength and agility, sharp claws and splitting mouth

Weaknesses

Fusion Ben cannot normally be accessed unless inside the Omnitrix.

The first Fusion Ben, as a result of Ben's DNA's instability at the time, suffered severe brain degeneration, combined with extreme anger towards everything. This resulted in the fusion being little more than a gigantic rampaging beast. This weakness was not shared by the second Fusion Ben, who had Ben's intact mind.
