Spectra is one of the several Green Lanterns from different parallel universes who joined together to discover what was happening on earth 15. Along with Len Lewis, Green Lantern from earth 6, she felt the coming of the Anti-Man and went on a direct confrontation against Zundernell, the Golden Lantern.

At difference of the other Lanterns, Spectra seems to manipulate all the range of the visible spectrum, not only the green and uses power prisms in her hands instead a power ring. These traits and her name could be related to her possible earth of origin and who she could be analog of.
