This version of Benjamin Kirby Tennyson is from an alternate Universe that closely parallels the Prime Timeline. Ben was defeated by Khyber the Huntsman, successfully removing his Omnitrix arm and experimented on by Dr Psychobos. They permanently bonded the Nemetrix to him to further push its limits, resulting in Ben becoming a savage animal. Khyber utilises him as his ultimate hunting animal, preying on the fiercest game in the Galaxy.

• Feral Ben is currently 16-Years-Old.

• Unlike the Omnitrix, the Nemetrix can transform its non-sapient user into a predatory species, mainly catered for certain transformations in the Omnitrix. It was originally built by Dr Psychobos.

• Ben was defeated through ambush by a team consisting of Khyber, Dr Psychobos, Dr Animo, and Malware.

• His Omnitrix arm was dismantled by Malware and Psychobos to further enhance the Nemetrix. The outer casing as well as Ben’s arm is on display in Khyber’s trophy room.

• Despite its upgrades, the bio-feedback of the Nemetrix still corrupted Ben’s mind to the point of acting like a savage animal. Forgetting his entire life and family in the process. Use of the Nemetrix has affected his human biology.

• The only thing Khyber feeds him is chilli fries once a day.

• Feral Ben has access to 25 regular predator transformations. They are triggered and controlled by Khyber’s unique whistle.

• Eon travels to his Universe in order to recruit him in hopes to rule the Omniverse. But they will come in conflict with Ben Prime and Professor Paradox.

• Eon buys a whistle identical to Khyber’s frequency from the hunter himself. Khyber got a hefty price to allow Eon temporary use of Feral Ben.

Due to the Nemetrix bio-feedback, Feral Ben has no resemblance of a human personality, acting like a rabid animal who constantly wants to bite and scratch people. He has no agency and must rely on an owner to control him. Ben is even worse when he is in predator-alien form, becoming more aggressive and monstrous as a result.
