The Symbiote Saga
Mary Jane became possessed by the Carnage symbiote, becoming the Carnage Queen. She overwrote the symbiote's obsession with chaos and converted Midtown High into a hive, creating increasingly sophisticated and powerful symbiote-creatures. Michael Morbius seized control of her using a device planted on her head, but when it was removed MJ was able to force the symbiote away from herself and it was destroyed. Afterwards Mary Jane appeared to revert back to normal, but secretly retained her symbiote powers.
With the help of Doctor Curt Connors, Mary Jane learned full control over her symbiote powers. She kept this a secret from Peter, knowing he'd try to recruit her into the Web-Warriors and not wanting her new powers to interfere with her plans for her future. She was able to hold her own against Kaine, a defective Synthezoid with Spider-Man's powers, and helped Peter track him to one of Doctor Octopus's secret lab. Attacked by Kaine and its brethren, Mary Jane revealed she had retained the symbiote and dubbed herself Spider-Woman. Fighting side-by-side with Spider-Man and the Scarlet Spider, she bickered with Peter over her decision to keep her powers secret and initially rejected his offer to join the Web-Warriors. While Peter and Ben accompanied Doc Ock to Hydra Island, Mary Jane returned to the Triskelion and alerted the Web-Warriors to the situation. Annoyed by their patronizing attitude towards her, MJ transformed into Spider-Woman and quickly trounced them. She and the Web-Warriors helped Spider-Man fend off Hydra's Weapon S Synthezoids long enough for Ben to overcome his inner darkness, and hinted that she was reconsidering her refusal to join the team.
As Spider-Woman, Mary Jane retained all the powers of the Carnage symbiote and possesses superhuman powers as a result. She can create weapons using her symbiote powers such as blades or maces. Her symbiote powers also enable her to generate web-lines she can use to swing from.
- Voiced by Tara Strong.
- After the exclusive with Spider-Man, MJ told Peter that she wished that Spider-Man would let her see who he really is, and Peter answered that she would maybe get another chance.
- She finally did later in the series.
- Her role in the series in wanting to work at the Daily Bugle and as a spider themed hero somewhat reflects that of mainstream Peter Parker's as a crime fighter and a photographer for the Bugle.
- Mary Jane appears in Spider-Man's imagination throughout the series.
