Devoison (Battle Ben-OH).jpg

Devoison is the Omnitrix's DNA sample of a Necro Aries from Anur Phaetos' moon, Anur Patoll, in the Anur System. Devoison was inspired by Black Sheep, created by Bence Szilágyi.


Devoison has the appearance of a ghost sheep, being made of purple flames, with a horned skull as his face and limbs which consist of bones. He has small green eyes and no visible mouth or nose. He has a spirit parasite on his tail and the Omnitrix symbol is located on his forehead. He also has two spiked horns on his head.

Powers and Abilities

Being made from bones and flames, he is technically invulnerable, immortal and he can't be stunned.

His flames can set basically anything on fire, although the flames are controlled by the parasite on his back, which is very animalistic and bloodthirsty, and cannot be controlled by Ben.

With his flames he can bring dead bodies back, but they won't be truly alive, just being able to perform actions as Devoison commands, just like puppets. By removing his control over them, they will "die" again, and just like vampires, he can drain life force from other beings.

Similarly to Lucky Beat, he can manipulate probabilities, but he cannot do it on command and can only bring bad luck to others.


He is basically a walking disaster, capable of causing any kind of serious damage unwillingly to his allies due to his flames or the bad luck that he brings.

If his head is separated from the rest of his body, it will become inert, and the parasite will be no more, until the body is brought back together.




  • His name is made from the words 'Devil' and 'Poison'.
  • In the Battle Ben timeline, the Anur System has an additional planet and a moon, Anur Kaster and Anur Patoll. The first was added after a part of the system entered the Null Void for a few solar cycles, and a few of the Null Void's inhabitants came to Anur along with their planetoid, later evolving into the Succubians. The latter came to be after a strong and 'abnormal' cataclismic event struck Anur Phaetos, making chunks of the planet leave into orbit, and creating a moon for Anur Phaetos. There, the Necro Aries evolved from the dead energy of the system, while the Summoniom Patroms evolved to see the true nature of the system.
