Diamondhead was mutated by a diamond-powered laser while attempting to steal some precious gems. He developed a hard, diamond-like body that was superstrong. He used his new abilities to enhance his criminal career.

After being defeated by Nova, he forms the criminal gang Terrible Trio with Condor and Powerhouse. After Condor is defeated by the Sphinx, Diamondhead allies with the Sphinx and Doctor Sun. Along with his allies, Nova, and the Champions of Xandar, Diamondhead goes to Xandar on Nova’s spacecraft.

Once there, Diamondhead betrays the Nova Corps to the Skrulls. This causes the death of one of the Champions, and Diamondhead is left to float in space.

Later, Diamondhead was seen as a prisoner on the Stranger’s laboratory world. He escapes and returns to Earth.

Following the Stamford incident, the identities of the New Warriors were publicly leaked, including Nova’s. Diamondhead uses this information to locate Nova’s parents’ house and patiently waits until his nemesis comes home. When Nova returns to Earth after the Annihilation War, Diamondhead attacks him. Nova easily defeats Diamondhead and takes him back to prison.

As part of the Marvel NOW! event, Diamondhead ambushes the new Nova, but is easily defeated and left stranded in the desert.

Powers and abilities

Diamondhead’s body is basically one large diamond, making him incredibly strong and incredibly resistant to injury and harm. According to Nova, he can regrow destroyed limbs, given time.
