Omni-Splicer Diamondhead is the Omni-Spliced version of Diamondhead in E-10: Horizons. He is spliced with Antrosapien DNA.


Omni-Splicer Diamondhead's appearance is based on Diamondhead's appearance in Season 2. However, he has golden armor on his chest, a golden helmet golden armor covering the entirety of both fore arms, and golden armor on his calves. Unlike his base form, his feet are exposed. His shoulders now have spikes coming off of them. The spikes on his back are now made of a golden energy. Each of his fore arms has two spikes of golden energy. There are two energy spikes on his chest piece, and he has a mowhawk made of the energy, as well. Crystal growths can be seen coming from his back and helmet. He wears the Omnitrix on his chest.

Powers and Abilities

Omni-Splicer Diamondhead retains Diamondhead's powers.

Given his Antrosapien DNA, Omni-Splicer Diamondhead is now able to produce sonic screams, and as such, is more resistant to them than his base form, although he can still succumb to them.

Omni-Splicer Diamondhead has the ability to generate energy weapons. Omni-Splicer Diamondhead's helmet has a trapdoor-esque mouth guard.


Omni-Splicer Diamondhead retains Diamondhead's weaknesses.

When he creates energized crystalized constructs, they can be absorbed like energy.
