The Ultraviolet Orb is a Lanu Orb that holds Novuscurous's third spirit, Radioton. It was held in Zythurvion's Lost Chamber, and Lanuwigi beat thecaptain64000 to this orb and corrupted him with it. Then LuigiFan54321 knocked Radioton out of Captain, giving the heroes another Lanu Orb. It seems to be associated with items on Zythurvion, being of a purple color. It's theorized the orb is made of Zyther Crystals.
