Official Site Biography

Malcolm Calcite was a physicist experimenting with laser refraction through various materials, when an earth tremor destabilised his apparatus and focused a beam of high-energy refracted laser light on him! His body reacted by turning permanently transparent and totally internal reflecting the light. He can now change his refractive index at will, bending light and creating cool rainbow effects, but cannot set it to exactly 1 so that he is actually invisible.
