Chromastone is a playable alien.
Chromastone is a super dense silicon life-form able to absorb energy like a conductor and channel it into laser blasts or less - intense natural light. He can also allow it to pass harmlessly through his body via refraction which can also be blasted back at the foe. Chromastone can seemingly produce blasts without having to absorb energy, though it may be due to absorption of radiant energy like sunlight, or streetlamps or just ambient energy.
It is a crystalsapien. It is somehow related to Petrosapien, species of Diamondhead as shown in Secret of Chromastone.
