Ravonna Renslayer was the daughter of King Carelius, a ruler in the 40th century Earth. She became the beloved of Kang the Conqueror after he had tried to conquer her Earth. During a battle between Kang's forces and rebels and the Avengers on the other side, a rebel soldier tried to shoot Kang, but Ravonna, realizing she was in love with Kang, threw herself in front of the bullet, thus saving his life, but falling into a coma herself.

Kang preserved Ravonna's lifeless body in stasis. When the Grandmaster challenged him to a game, he promised Kang the power over life and death, thereby giving him a chance to revive Ravonna. However, the angry Kang chose the power of Death in order to kill the Avengers. This scheme failed, however, as Kang didn't take into account the presence of the Black Knight, who was not at that time an Avenger. Ravonna was later revived by the Grandmaster, who showed her the choices Kang had made. Ravonna grew bitter about Kang's failure to save her, and swore to avenge herself on him.

Ravonna's first plot saw her appearing to the then Avenger Doctor Druid in visions in order to gain his help in securing a highly powerful weapon, the Ultimate Nullifier. Disguising herself as the space pirate Nebula, she attempted to infiltrate the Council of Cross-Time Kangs, while stepping up her scheme to control Doctor Druid. She influenced him to take over leadership of the Avengers, manipulating his teammates with his psychic abilities to vote him in as chairman. With Druid and the rest of the Avengers under her power, Ravonna made them accompany her into a timestorm to retrieve the weapon. She was opposed, however by three members of the Council of Cross-Time Kangs, as well as the Avengers, who managed to shake off Druid's control. One of the Avengers, She-Hulk, battled Ravonna herself. Ravonna was apparently lost in the timestorm along with Druid.

Ravonna later attempted to influence the Fantastic Four into freeing her from the timestorm and helping her gain the Ultimate Nullifier, but her plans were thwarted by the team. She later escaped the timestorm, onto Earth-616 in the year 1961. This time she was defeated by a younger version of Druid, before she tried to take control over him again.

She later took on another guise, that of the Terminatrix, to battle Kang himself. Kang sacrificed himself so that she could live. Ravonna ruled over Kang's kingdom Chronopolis in Kang's stead, before eventually tiring of the role and reviving Kang, once to kill him, and again to reconcile with him, until they grew tired of one another.

Ravonna was reported as having been killed in the destruction of Chronopolis, though whether she will resurface once again despite this is unknown.
