First Appearance:

A Look Back at Feedback

Grey Matter is the Omnitrix's DNA sample of a Galvan from the planet Galvan Prime.


Grey Matter's appearance is that of his original series counterpart, although he has a reversed outfit.

In A Look Back at Feedback, Grey Matter wears his Omniverse outfit.


  • Grey Matter retains all of his powers from the original canon.


  • Grey Matter retains all of his weaknesses from the original canon.
  • In A Look Back at Feedback, Azmuth confirms that, as neither he nor Albedo were the DNA donor for Grey Matter, he has no special information about the Omnitrix in all of his intelligence, therefore he cannot change certain things about the device, such as Azmuth's lock on Feedback.

  • Grey Matter first reappeared in A Look Back at Feedback when he was going to undo Azmuth's lock on Feedback, only to have his confidence diminished by Azmuth and decide against even trying.

RAT Timeline

  • Grey Matter unintentionally appeared to fight Eon in Lie as Old as Time. He temporarily ripped Eon apart with the containment unit housing the Hands of Armageddon.
