Origin
In the latest incarnation of the Uncanny Avengers, Luminous appears to Scarlet Witch and Quicksilver as they attempt to find answers concerning their parentage and taunts them as she displays an upgraded combination of their power sets. She has a lofty opinion of herself and is absolutely subservient to the High Evolutionary.
Powers
Luminous wields immense power, able to manipulate Chaos Magic with more accuracy than the Scarlet Witch and (theoretically) capable of accelerating faster than Quicksilver. She has also displayed self-propelled flight and force field construction, but the origin and limitations of these abilities are as of yet unknown.
