Grey
Grey Matter is one of Ben Tennyson's alien egos from the first Ben 10 Series.

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

He is voiced by Richard Steven Horvitz who also voiced Billy, Daggett The Beaver, Lugosi, Zim in the original series, Carlos Alazraqui in Race Against Time and Eric Bauza in Omniverse.

Appearance

He is a Galvan, a gray frog-like alien that is five inches tall. The Galvans are a highly intelligent race responsible for many of the technologies shown in the series, including the Omnitrix, the Null Void Projector, the Null Void, their planet, Galvan Mark II (since the Highbreed destroyed their original homeworld, Galvan Prime, in the "Alien Force" two-parter "War of the Worlds"), and the Galvanic Mechamorphs (Upgrade's specie).
