Grey Matter is a Galvan from Galvan Prime.


Grey Matter is a grey-skinned, frog-like, bipedal alien that is only four inches tall with large green eyes, which have rectangular pupils and horizontal eyelids.He wore a white jumpsuit with a thin vertical black stripe down the front, his eyes were green, his forehead had a larger version of the jumpsuit's stripe.

Powers And Abilities

Grey Matter's 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, something only Ken has demonstrated.

Grey Matter's brain capacity makes Ben smarter about things he has never even seen before, like Kraab's alien circuitry.

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 skin. He also has sharp teeth that can cause pain to those he bites, as well as slimy skin that makes him difficult to grab.

Grey Matter was the weakest alien in the original series 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, as he was strong enough to hold a Badland Eagle.

Grey Matter can breathe underwater due to having gills, making him amphibious.

Grey Matter has a long prehensile tongue, owing to his insectivore nature. As a Galvan, he also possesses a 'pre-brain' which deals with all basic bodily functions.

Grey Matter was able to understand Pyxi's speech.


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.

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 where babies come.

Being a Galvan, Grey Matter would be vulnerable to being trapped by a member of Omnivoracious's species if they were not extinct.
