Bouldercrash is the Omnitrix's DNA sample of a Mimetiterran from the planet Geawde III in Universe-7781.


Bouldercrash is a humanoid blue gooey alien with rocks on his limbs and head. The Omnitrix is on his chest.

Powers and Abilities

  • Shapeshifting: He can manipulate his liquid-like body.
  • Elasticity: He can stretch the blue parts of his body.
  • Adhesive Body: He can stick materials, such as boulders, to his body.
  • Sharp Teeth: His teeth can bite through steel.
  • Enhanced Durability: He can absorb the material around him to create strong armor.
  • Cannon Hands: He can turn his hands into cannons to launch the materials he's collected.
  • Camouflage: He can blend into his environment.


  • Weak Body: His actual body is weak compared to his armor.
  • Environment: He needs to collect materials from the environment to make armor so this can put him at a disadvantage if he has nothing to absorb. To combat this weakness the Omnitrix provides him with strong rocks to use as armor.
  • Material Composition: He cannot process materials that are incredibly durable, with elements such as Taydenite being too durable for him to process.




  • This alien was not made by me. The idea for him came from PerryPorkchoP and his design came from Kuro the Artist. To see the original alien go here.
  • I was given permission to use this alien by PerryPorkchoP.
  • Bouldercrash's mannerisms and personality can at times overwhelm Ben, leading him to become increasingly verbose, swearing frequently and at times compulsively mentioning apparently random facts, akin to Tourette syndrome. Bouldercrash is a tad dim-witted, tending to talk for the sake of talking.
