Diamondhead has his Heroes United appearance. Instead of being encased in rocks, he wears a white uniform with a green arrow-like stripe running through the middle and black pants with white soles.
Ben slams down the Infinimatrix's dial and is engulfed in a green light.
Ben hovers in a dark green background, with light green bubbles pulsating rapidly behind him, as he crouches down. His skeletal structure increases, with him becoming taller and more muscular. Pale green crystals start developing on his arms and torso, before completely covering him from head to toe. Two large shards emerge from his back, along with two smaller ones on his lower back. His lower jaw becomes wider, with a shard protrusion growing on the back of his head. The crystal around his shoulders slightly tilts up and his elbows grow crystal spikes. A sleeveless bodysuit forms around him, with a green V-shaped stripe. The part above the stripe is colored white, while the lower part is black, with the boots having a white trim. Diamondhead opens his green glowing eyes, which have a crystal texture, as the Infinimatrix symbol pops out of his chest. Diamondhead smiles and puts his arms at his sides, striking a confident heroic pose, completing the transformation.
Powers and Abilities
Diamondhead's body is composed of extremely thick organic pale green crystals. He has the ability to manipulate the atomic structure of his physiology at will, allowing him to form his limbs into diamond weapons such as blades and bludgeons. Moreover, he can control all the crystals he generates, to the point that he can make them explode or lift them off the ground. He can fire crystal shards sequentially out of his hands and can explode his body parts into crystalline formations.
Diamondhead can make monstrous and large clusters of crystals, conjuring walls and forming crystal shields and ramps. He can also generate crystals from the ground at a distance, can reshape his projectiles into limited shapes, and can also form gaping hands to capture enemies. Diamondhead is capable of encasing enemies in crystals, and can create crystals inside of objects and cause them to spike out.
Diamondhead's crystalline body resembles a living prism, allowing him to deflect and absorb most energy beams and render weapons similar to lasers useless by simply refracting. Similarly, rays generated by dimensional transporter devices will reflect off of Diamondhead's body.
Diamondhead has inhuman physical abilities.
Diamondhead is quite strong.
Due to the natural density of crystal, Diamondhead is extremely durable to physical impacts.
Diamondhead is resistant to fire and heat, such as that generated by a Pyronite, much like an ordinary diamond.
Because he is made out of organic crystals, Diamondhead is immune to aging. Therefore, he is impervious to time rays generated by a Chronosapien, as diamonds do not age.
Diamondhead can regenerate, but to a limited extent. He can also extend his arms, which allows him to propel himself upwards by pushing against the ground.
If under the effects of a cold virus, Diamondhead is able to sneeze out tiny sharp crystals from his mouth. It is unknown if he can do this when he is not sick, however.
Despite his enhanced durability, Diamondhead's body can crack and shatter if he's impacted with enough force.
Diamondhead is especially weak to sonic vibrations, such as a Loboan's sonic howls and an Evolved Sonorosian's Sonic Disks. Either one of these scenarios can render Diamondhead unconscious.
While Diamondhead can regenerate, there is a limit to how much damage he can recover from.
Despite being fireproof, Diamondhead still feels pain against fire attacks when he is caught off-guard. Also, Diamondhead's shard projectiles can be dissolved by an Evolved Methanosian's fire blasts.
Diamondhead can be easily blinded by a Lepidopterran's slime should it get all over his face.
Diamondhead can slip on certain surfaces, such as ice generated by a Polar Manzardill.
The two shards on his back can also leave him stuck on a wall or on other surfaces that he gets knocked into. Gwen as Diamondhead, however, lacks this weakness.

- Due to the events of The Secret of Chromastone not occurring in this timeline, Diamondhead and Tetrax are the only Petrosapiens alive.
- In Timeline 1 of Earth-50, certain Petrosapiens may inherit Crystalsapien features as it is a recessive trait. Diamondhead does not have any Crystalsapien features as his DNA donor did not inherit any of them.
- Diamondhead makes a crystalline metallic sound every time he moves.
- Diamondhead was named by Max in And Then There Were 10.
- Diamondhead has been Ben's favorite alien since he was 16.
