You're in trouble, Albedo. I've had a lot of practice with this one.

Exodus Diamondhead.

As Diamondhead, Kenji'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, as well as make crystal constructs grow from his body, the latter of which he used to protect Gwen from a falling tree by making large crystalline spikes quickly grow on his back and then retract again.

Kenji 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.

Kenji'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.

Kenji has inhuman physical abilities.

Kenji is quite strong.

Due to the natural density of crystal, Kenji is extremely durable to physical impacts.

Kenji is resistant to fire and heat.

Because he is made out of organic crystals, Kenji is immune to aging.

Kenji 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, Kenji 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.

Weaknesses

Despite his enhanced durability, Kenji's body can crack and shatter if he's impacted with enough force.

Kenji is especially weak to sonic vibrations.

While Kenji can regenerate, there is a limit to how much damage he can recover from.

Despite being fireproof, Kenji still feels pain against fire attacks when he is caught off-guard.

Kenji's powers are ineffective against extremely tough opponents.

Kenji can slip on certain surfaces.

The two shards on his back can also leave him stuck on a wall or on other surfaces that he gets knocked into.
