Oh, man! Diamondhead and Grey Matter? I'm a razor-sharp hood ornament.

– Ben after turning into Diamond Matter.

Diamond Matter is the combination of Diamondhead and Grey Matter's DNA. He cannot be accessed unless the faceplate of the Omnitrix is broken or by using the Biomnitrix.[note 1]

Appearance

Diamond Matter is slightly bigger than Grey Matter. He has Diamondhead's crystalline skin, as well as the spikes on his back and head, and Grey Matter's eyes and mouth.

Diamond Matter wore a uniform that was white with black cuffs on the left and black with white cuffs on the right, and wore the Omnitrix symbol on his chest.

Powers and Abilities

Being part-Petrosapien, Diamond Matter can alter the shape of his limbs and fire diamond shard projectiles much like Diamondhead.

Being part-Galvan, Diamond Matter's intelligence is at the same level of Grey Matter, allowing him to fire his diamond shard projectiles with excellent precision.

Weaknesses

Unlike Diamondhead, Diamond Matter's enhanced strength is reduced to a level similar to Grey Matter because of his size.

History

Ben 10

  • Diamond Matter first appeared in Dr. Animo and the Mutant Ray, where he battled Heatbat and briefly got eaten, then thrown up by an alligator. He then sliced his way through some swamp trees to clear the gang's airboat's path until he reverted.

Notes

  1. Diamond Matter, Heat Jaws, and Stink Arms are three fusions which were originally created by a broken, prototype Omnitrix. All three fusions are possible with the Biomnitrix, however, they might differ in aspects such as appearance, powers and weaknesses due to the fact that there's no evidence to support the idea that the broken prototype Omnitrix creates fusions the same way as the Biomnitrix.
