XLRArmBlastDiamondHeat is a fusion of XLR8, Four Arms, Heatblast, and Diamondhead.


He has XLR8's legs and tail, the latter of which has a mace on the end and spikes along the top, made from Diamondhead's crystals. His lower body is XLR8's with Four Arms' general proportions and arm count, the lower set keeping the structure of the ones belonging to Four Arms, but made with Heatblast's lava, with his upper spikes being made of flames. His upper body has Four Arms' general shape, and his upper set of arms belong to Four Arms, but he has gauntlets, spiked shoulder pads, and upper body armor, all made from Diamondhead's crystals. His head is Four Arms', but the mouth and crystal structure around it belong to Diamondhead.

XLRArmBlastDiamondHeat bears no Omnitrix symbol, as he was used while within it.
