This is his basic form of Cyber Grey Matter.
Powers & Abilities[]
Grey Matter can alter his size, whatever for small or big sizes. His small size belies his great calculative and technical intellect. He can create complicated machines from spare parts, understand the function of any device at a glance, and make sophisticated repairs to complex machines (such as a warp-drive engine).
Grey Matter's intellect serves as a problem solver and analytical help in difficult situations. This allows Grey Matter to think more strategically when brute force is inefficient. In fact, Grey Matter is smart enough to know how to unlock the original Omnitrix's Master Control.
Grey Matter's brain capacity makes Ben smarter about things he has never even seen before.
Grey Matter can sometimes manipulate living things by stimulating certain parts of their nervous system if such beings can be controlled by external stimuli.
Grey Matter's size allows him to squeeze into small spaces and can climb walls due to microscopic pads on his armor. He also has sharp teeth that can cause pain to those he bites, as well as slimy armor that makes him difficult to grab.
Grey Matter was the weakest alien due to his minuscule size, but he compensates with his intellect and efficient technological and calculative skills.
Grey Matter's intelligence is not limited to technology and biology, as he is smart in general. Even if he does not know something, he can learn it very quickly.
Grey Matter appears to be stronger than he looks.
Grey Matter can breathe underwater due to having gills, making him amphibious.
Grey Matter has a long prehensile tongue, owing to his insectivore nature. He also possesses a 'pre-brain' which deals with all basic bodily functions.
Weaknesses[]
Grey Matter's small size makes him unsuitable for physical battle, so he must outsmart his enemies in a fight. Animals like dogs and cats can be a problem, as they may see Grey Matter as a chew toy or food to them.
Despite possessing immense intelligence, Grey Matter can still make miscalculations, as his attempt to upgrade the Rust Bucket's air conditioner caused it to overheat instead, incapacitating the vehicle.
According to himself, Grey Matter sometimes does not know what he is talking about.
Grey Matter does not know everything, as seen when he (initially) did not know which galaxy his species is from.
Being a Galvan, Grey Matter would be vulnerable to being trapped by a member of Omnivoracious's species if they were not extinct.
