Real Name: Phylla-Vell (Unconfirmed)

Quasar carries a pair of Quantum Bands, which let her control quantum energy in various ways, forming constructs, shields, energy blasts.  She has the ability to fly.

Quasar is a member of the Guardians of the Galaxy.

Note: In the mainstream Marvel Universe, Phylla-Vell is the daughter of the original Captain Marvel (the Kree Mar-Vell) and Elysius, an Earth Eternal.  However, in the AEMH universe, Captain Mar-Vell is quite different, and the Eternals have yet to be introduced, so we have no confirmation of her origin or species.
