She later recovered, and returned to Earth to kill Thor. She fought the original Thor and the third Thor, and then decided to "relax" on Earth for a while.
When Annihilus invades the positive universe with the Annihilation Wave, Stellaris submits herself to superpowered extraterrestrial martial artist Gamora, becoming one of Gamora's "Graces" to order to oppose the threat.

Powers and Abilities
Stellaris is an athletic woman with no superhuman powers, although she is skilled in her native world's equivalent of street-fighting techniques. Stellaris possesses a suit of "living" armor of unknown origin and composition. In one story her armor was assessed by a robot to be identical to the armor of the Celestials. She can mentally will the armor to reshape itself to her specifications, and even cause it to increase or decrease in size and mass. Hence, she can cause the armor to become much larger and more massive than herself, cause it instead resemble a form-fitting jumpsuit, or even cause it to take on the appearance of normal terrestrial clothing. Stellaris can also will the armor to form a vast array of weaponry and vehicles. Examples so far observed include armament that fires blasts of concussive energy and intense heat and a "sonic shatter-pistol." She can cause part of her battlesuit to become an advanced skycycle or even to become a vehicle resembling a normal Earth motorcycle that can nevertheless fly through the air. Stellaris's battlesuit is said to contain power on the level of the 's. The battlesuit contains a self-destruct system that will cause the battlesuit to implode, releasing enough concussive force to destroy a planet. The battlesuit is capable of both atmospheric flight and interstellar travel.
