Unrevealed, but she is the sole survivor of her world
Place of Birth
Thor #419 (1990)
Following Thor and Hercules, Stellaris soon found herself in New Wundagore, home of the High Evolutionary. She modified her armor to something stealthier and stowed away on his ship to find some new weapons she could use in her crusade against the Celestials. After disposing of a few guards, Stellaris freed the imprisoned Nobilus, one of the High Evolutionary’s New Immortals. Thor tried to stop the rampaging godling as Stellaris used her armor to tap into the ship’s computer system. Learning all she needed to, Stellaris grabbed Nobilus and exited the ship.

Stellaris kept to the shadows, revenge far from her thoughts, as she followed Masterson, now Thunderstrike, secretly aiding him against such foes as Bloodaxe and the Juggernaut. She decided to reveal herself when she came to the aid of Thunderstrike and Spider-Man in a battle against S.H.I.E.L.D. and their Man-droid troopers, but left again soon afterwards. Surprising Masterson again at a later date, she had helped Thunderstrike against foes like the Absorbing Man and the Heliopolitan Death god, Seth. However, questions were raised about her mysterious powers when the Absorbing Man tried to soak up her powers and
Stellaris recently turned up on the planet Godthab Omega after the Annihilation Wave started its path of destruction on the universe, and allied herself with Gamora becoming one of her Graces. She, and her ally Nebula, attempted to take on Ronan but were defeated by the superior power of his Universal Weapon. Stellaris was left badly injured and in need of medical treatment, and it can be assumed that she is still recovering from her recent battle with Ronan.
