Photon's armor was the unique armor of the Knights of Meyer's Captain Photon. Photon had the armor polished in chromium, which had been salvaged from a specialized skyfighter that had once belonged to Mr. Stupid NoHead of the NoHeads, the Knights' precursor.
The chromium finish on the armor helped reduce radiation, but Photon primarily wore it as a symbol of past power. Photon also wore her armor with a traditional Knight of Meyer armorweave cape. Her armor's gauntlets were modified and precision-crafted for crushing. Photon claimed that not even a top-class boxer could crush this armor when she was threatened, though she chose to relent rather than see if her boast was true.
