Grey Matter (Earth-1010)

Grey Matter is the Omnitrix's DNA sample of a Galvan from the planet Galvan Prime in Earth-1010.

Appearance
Grey Matter is a 6 inch tall humanoid who, as his name suggests, has grey skin. He has a large head with huge green eyes. his hands and feet are also disproportionately large given his size. The Omnitrix dial is on his back.

Delta Dimension
In the Delta Dimension, Grey Matter's head is rounder and his eyes are orange.

Powers and Abilities
Grey Matter is, in terms of raw IQ, Ben's smartest alien. He specialises in technology and biology. He can create complex machines from spare parts, understand a machine's function easily, and make sophisticated repairs to complex machinery with little prior experience.

Using his knowledge of biology, Grey Matter can stimulate large creatures in order to manipulate/control/incapacitate them such as exploiting pressure points.

Grey Matter's small size allows him to climb inside tight spaces, such as inside machinery. He can scale walls thanks to suction pads on his skin.

Weaknesses
Being so small, Grey Matter is fairly fragile. He struggles to fight opponents larger than himself.

When it comes to physics and related subjects, Brainstorm outranks Grey Matter in terms of intelligence.

History
Grey Matter was one of the aliens used by Ben 10'000 to invent the Biomnitrix. Much to Ben 10'000's annoyance, Ken figured out how to use Grey Matter to unlock the Master Control in his Omnitrix. Both of these events took place in the future of the Prime Timeline.

Ben 10: Reboot Revolution
Grey Matter was briefly used by Delta Ben 10'000 in Ten Over Ten Thousand to avoid his photograph being taken.
