Grey Matter(Gwen 10)

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

Appearance
In the original series, Gwen as Grey Matter has Gwen's hair and more oval shaped eyes, with much smaller pupils. She wears a light blue jump suit with dark blue sleeves. She wears the Omnitrix symbol on her back. She also lacks the stripes Ben's form has.

In Aliens Unleashed, 16 year old Grey Matter looks exactly the same as Fergi.

Powers and Abilities
Grey Matter's small size belies his great calculative and technical intellect. He can create complicated machines from spare parts and understand the function of any device at a glance. Grey Matter's intellect serves as a problem solver and analytical help in difficult situations.

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 tiny suction cups on his skin. He also has sharp teeth and his slimy skin makes him difficult to grab.

Grey Matter appears to be stronger than he looks, as he was strong enough to move a cleaner's bucket with mops in it in Ultimate Weapon, and in So Long, and Thanks for All the Smoothies, he was able to break a coolant pipe to freeze the Vreedle Brothers.

According to Derrick J. Wyatt, Grey Matter is amphibious and has gills.

Grey Matter has a long prehensile tongue, owing to his insectivore nature.

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.
