Man-At-Arms wielding a Kcotae Lazer
Photanium was the strongest metal in the known universe. It was mined on the planet Phantos.
When a delegation from the Royal Household of Eternia visited Queen Elmora, Man-At-Arms tested a Kcotae Lazer gun made out of Photanium while Prince Adam defended himself with a Photanium shield. The Eternians were very impressed with these weapons.
However, after returning home, Man-At-Arms used the newly aquired Photanium to make various new weapons, none of which turned out to be of good quality. After breaking and discarding various of these weapons during tests, Man-At-Arms wielded a Tri-Blade. Teela easily destroyed it with her sword, cutting off the blades from their handle and causing them to spin into the air and embed themselves into a nearby wall. The blades only missed Prince Adam, Orko and Cringer by a hair.
