He has one arm of Four Arms on his right side and 3 arms of Grey Matter on his left side. His right leg is Grey Matter's and left is Four Arms'.
Grey Arms wears the Omnitrix symbol on his chest.
Powers and Abilities
Grey Arms, being half Tetramand/half Galvan, has enhanced strength, albeit he's not as strong as a Tetramand due to the asymmetric body of the fusion and not being pure. He also has shown higher intelligence, probably coming from his Galvan part.
Due to his asymmetric body and having one functionally strong arm, he can't use his enhanced strength. In addition, he suffers from imbalance issues.
- Riding the Storm Out (first appearance)
His name is the combination of Grey Matter and Four Arms.
- Grey Arms is the first fusion alien in the reboot continuity.
