Avengers #264 (1986).
Rita DeMara first appeared in Avengers #264, published in February 1986. She was co-created by writer Roger Stern and artist John Buscema. Her introduction came during a period of significant change for the Avengers roster and served to reintroduce the Yellowjacket mantle, which had been unused since hank_pym abandoned it.
Stern and Buscema introduced Rita not as a new hero, but as a professional criminal, a skilled technician who opportunistically steals the Yellowjacket technology. This immediately set her apart from her predecessors. Her initial role was as a formidable new member of the Masters of Evil for the upcoming epic storyline, Avengers: Under Siege. Her creation provided a character with a direct legacy link to a founding Avenger but with a completely contrasting moral compass, creating instant narrative tension and a compelling path for future development from villain to anti-hero to full-fledged Avenger.
The origin of Rita DeMara as Yellowjacket is a story of ambition, opportunity, and a long, winding road to redemption. Unlike many super-powered individuals, she was not born with powers, nor was she the victim of a lab accident; she actively sought out the power she would wield.
Rita DeMara was a highly skilled electronics expert and professional criminal. Seeking to elevate her status in the underworld, she learned of the abandoned laboratory of Dr. Henry “Hank” Pym, the original Ant-Man and Yellowjacket. Infiltrating the Leonia, New Jersey facility, she discovered one of Pym's older, discarded Yellowjacket costumes along with a supply of his size-altering “Pym Particles.” A brilliant technician in her own right, Rita didn't just steal the suit; she studied and modified it, customizing its systems to her own specifications. Her first major outing as the new Yellowjacket was an attempt to prove her mettle by defeating Pym's ex-wife, Janet van Dyne, the_wasp. The ensuing battle showcased Rita's competence but ultimately ended in her defeat. However, her impressive performance caught the attention of Baron Helmut Zemo, who was assembling a new, formidable incarnation of the Masters of Evil. Rita eagerly accepted his invitation, seeing it as her ticket to the big leagues of super-villainy. As a member of the Masters, she played a key role in the infamous “Under Siege” event, where the villains successfully overwhelmed and captured avengers_mansion. During the siege, she clashed with the Wasp again, as well as Hercules and other members of the team. Though the Masters were eventually defeated by a rallying force of Avengers, Rita's reputation as a serious threat was solidified. After being apprehended, she was imprisoned in the high-security facility known as the Vault. This period marked the beginning of her turn towards heroism. During a prison riot orchestrated by Iron Man's nemesis, the Controller, Rita found herself fighting alongside the Avengers and other heroes against the rampaging inmates, a first taste of using her powers for good. Though she was later transferred to the female-only super-prison run by superia and joined her Femizons, her dissatisfaction with the villainous lifestyle was growing. A pivotal moment occurred when she was accidentally transported to the 31st century. There, she encountered the original guardians_of_the_galaxy, a team of freedom fighters led by Vance Astro. Initially abrasive and self-serving, Rita gradually formed a bond with the team. Stranded in a future far from home, she fought alongside them against the alien Badoon and other threats. This extended period was her heroic crucible; she learned about teamwork, sacrifice, and the satisfaction of helping others. She developed a close, almost romantic, relationship with the team's powerhouse, Charlie-27. After helping the Guardians in numerous battles, they managed to find a way to send her back to her own time. She left the 31st century a changed woman, having earned the respect of the Guardians and discovered her own heroic potential.
Rita DeMara has not appeared, nor has she been mentioned, in the Marvel Cinematic Universe.
The Yellowjacket identity and technology were adapted for the MCU, but in a completely different context. In the film Ant-Man (2015), the antagonist is Darren Cross, a former protégé of Hank Pym. Consumed by jealousy and ambition, Cross rediscovers and militarizes Pym's shrinking technology, creating a heavily armed and armored battlesuit which he dubs the “Yellowjacket.”
Key Differences from Earth-616:
The adaptation of the Yellowjacket as the primary villain of Ant-Man was likely done to create a clear “dark mirror” antagonist for Scott Lang's Ant-Man, a common trope in superhero origin films. It provided a direct technological and ideological opponent for the heroes to overcome. While Rita's story of redemption is a classic comic book trope, it may have been considered too complex for a villain in an introductory film.
Rita DeMara's effectiveness in both villainy and heroism stemmed from a combination of stolen advanced technology and her own innate skills.
Rita's power was derived entirely from her stolen and modified Yellowjacket costume. This suit gave her a suite of powers identical to those of Hank Pym and Janet van Dyne.
Rita's personality underwent a profound transformation. She was introduced as cynical, sarcastic, and purely self-interested. Her motivations were money and reputation. She possessed a sharp, biting wit that she often used to keep others at a distance. Her time with the Guardians of the Galaxy in the 31st century was the catalyst for her change. Forced into a heroic role, she discovered a surprising aptitude and, eventually, a liking for it. She developed genuine affection and loyalty for her new teammates, moving beyond her selfish origins. Upon returning to her own time, she was a more mature and responsible person, though she never fully lost her sarcastic edge. She actively sought to atone for her past, which led her to join the Avengers. She became a loyal teammate and a true hero, willing to lay down her life for others—a fact she tragically proved during The Crossing.
As Rita is not in the MCU, this section will analyze the Darren Cross Yellowjacket Armor for comparison. The MCU's Yellowjacket armor was not a suit for espionage or heroics but a prototype for a next-generation weapon.
The MCU armor was designed to look more menacing and militaristic, reflecting its purpose as a weapon of war. It sacrificed the insect-like grace of the comic versions for a more heavily armed, technological aesthetic.
This was Rita DeMara's debut on the main stage of the Marvel Universe. As a new recruit in Baron Zemo's massive Masters of Evil, she participated in the meticulous and brutal takeover of Avengers Mansion. She was instrumental in subduing the Wasp and was part of the force that overwhelmed and beat Hercules nearly to death. The storyline established her as a competent and dangerous villain and is considered one of the greatest Avengers stories of all time. Her role here provides the dark starting point from which her later heroism becomes so meaningful.
This storyline is part of her larger arc with the Guardians. While battling Doctor Doom in the present, Rita is accidentally flung into the 31st century. She materializes in the middle of a conflict involving the Guardians, the alien Stark, and the ever-present threat of the Badoon. Initially completely out of her element and focused only on getting home, she is forced to fight alongside the Guardians to survive. This arc showcases the beginning of her heroic turn, as she starts to care for the team and their mission. It's here she begins to realize that being a hero is more fulfilling than being a criminal.
This is the most tragic and defining event of Rita's life. After returning to the 20th century and joining the Avengers, she began to notice inconsistencies in Tony Stark's behavior. Using her technical skills, she investigated and discovered the horrifying truth: Iron Man was a traitor, a mind-controlled puppet of Kang/Immortus. Before she could warn the rest of the team, Stark confronted her. In a brutal and shocking moment, he murdered her in cold blood. Her death was the inciting incident that revealed the true scope of Immortus's plot, and her sacrifice ultimately helped the Avengers defeat him. The storyline itself is highly controversial among fans, but Rita's heroic final act is undisputed.
Years after her death, Rita was one of the many fallen heroes resurrected by the Chaos King (Amatsu-Mikaboshi) during his assault on reality. Reunited with other deceased Avengers like Captain Mar-Vell and the Swordsman, she fought bravely to push back the forces of oblivion. She demonstrated that even in death, her heroic spirit was undiminished. At the conclusion of the event, when Hercules restored reality, Rita was one of the few resurrected heroes who remained among the living, thanks to a “Chaos Cascade” of energy, officially bringing her back to the Marvel Universe for a new era.
While Rita DeMara's primary story is within Earth-616, the Yellowjacket mantle and her character have appeared in minor roles elsewhere.
Rita's unique position is that she is the only person besides Hank Pym to have a prolonged and character-defining heroic career as Yellowjacket in the Earth-616 universe.
Avengers #264 (1986).Avengers #393, part of the Avengers: The Crossing event.Chaos War event in 2010.Avengers: The Crossing storyline was highly controversial and many of its elements, particularly the idea that Tony Stark had been a sleeper agent for years, were later retconned as manipulation by Immortus, with the “real” Tony being replaced by a teenage version from an alternate timeline before both were eventually merged back together after the Onslaught event. Rita's death, however, remained canon.
