Obsorber is the Hidden Universe's DNA Sample of an Osmosian (Kevin's species), from the planet Osmos V. He was created by SoRandom31.

Back in Action: Alien Universe

  • In Hit and Miss, he was used for the first time but not in battle, he was used for Ben to get a fork for his food.
  • In Ten Plus Twenty, he was used by Ben to cage Nightcaster, then later on by an alternate timeline Gwen to shackle the alternate timeline Charmcaster.
  • In Missing Link, he was used to break Cyanne free of his power inhibitor.
  • In Revelation, he was used to remove Karin from the wreckage of her ship.
  • In The Alternative, he was used to absorb Darkstar's portal-conjuring abilities.
  • In Why Am I Here?, he was used by Albedo for the first time (as Negative Obsorber) to create a portal (after absorbing Overwatch's powers) to the Tertiary Wing for Bandit and Mosquito.


Powers and Abilities

Obsorber can absorb materials, and energy. Also, he is shown to have an ability to shapeshift his body parts in use for combat, which go alongside with his enhanced strength and durability.


  • Obsorber's existence came to life alongside Overbyte, Galeforce, Forecast, and Clinger, and was the 7th alien in total to be unique to Ben 10: Omni-Revolution. He eventually became an additional alien recycled for use in Back in Action: Alien Universe after the temporary cancellation of OR.
