Grey Arms

Grey Arms is a fusion of Four Arms' DNA and Grey Matter's DNA. He cannot be accessed unless the Omnitrix is tampered with.
==Appearance==
Grey Arms has the body of Four Arms, but the head of Grey Matter (although much larger). He has three eyes, two of which are those of Four Arms and one is a large Grey Matter's eye. 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 also has the upper head stripe of Four Arms, and his lower jaws is the same structure as a Tetramand. Unlike Grey Matter or Four Arms, Grey Arms has wrinkles on his upper lip.
Grey Arms wears the Omnitrix symbol on his chest.
==Powers and Abilities==
Grey Arms, being half Tetramand/half Galvan, has enhanced strength, albeit not as strong as a Tetramand due to the asymmetric body of the fusion and not being pure. He also has shown higher intelligence, presumably coming from his Galvan half.
==Weaknesses==
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.
