Ultimate Diamondhead is a slimmer physique with a white crystal body with faint pink and blue as the light reflects off his crystal body. The black suit covered most of his chest, wrapped around his raised crystal collar and framing his face. The top of his head was dome-shaped like a samurai hat. His fingers were floating around his palms.
The Ultimatrix symbol is located on his stomach.
- Enhanced Biology- Due to evolving into much slimmer physique, Ultimate Diamondhead is given higher agility and speed than the pre-evolved state.
- Crystallokinesis- Like it’s pre-evolved state, Ultimate Diamondhead is able to generate and manipulate crystals formed from its body. This evolved form has higher control as its fingers are floating, making them more flexible than they were before.
- Light Manipulation- Due to his crystal body, he is able to reflect light in order to become invisible, creating refracted illusions to trick enemies in a battle.
- Slimmer Physique- Due to the slimming down his body to be more mobility has caused them to lead to being less durable and strong as they once were before this evolution.
