Moonstone

Karla Sofen was once a respected psychologist who trained under the tutelage of the criminal . She even assisted Doctor Faustus in his grandiose attempt to take control of Manhattan Island. Faustus' plans never came to fruition however, due to the efforts of Captain America.[5]  As Cap rounded up Faustus' men, Sofen hid herself inside the baggage compartment of the doctor’s private 747, thus evading capture.

She later used her psychiatric credentials to gain access to the prison cell of Lloyd Bloch – the original Moonstone. Using hypnosis, she convinced Bloch that he was in fact a hideous, loathsome monster. The psychological trauma was so severe that it caused his body to reject the moonstone within him.

Energized by the emotional rush, Karla was able to absorb the essence of the moonstone through a sheer act of will. The intensity of the transfer was so great that it even granted Karla the ability to absorb Bloch's Moonstone armor into her own bodily tissue. With Bloch now powerless, Karla Sofen became the new Moonstone.[6]

A short time later, Moonstone decided to hire herself out to the subversive organization known as the Corporation. The Corporation sent Moonstone on a mission to Gamma Base inNew Mexico to purloin a top-secret piece of military hardware known as a Gammavator. She gained access as Dr. Sofen by offering professional help to fellow psychiatrist Leonard Samson, who had been impressed by Sofen's heterodox attitude at theUtrecht Coference. Once in Gamma Base, she opposed the gamma-spawned monster, the incredible Hulk. At first, Moonstone was able to provoke the Hulk into a savage frenzy, thereby earning her the sympathy of psychiatric colleague Doc Samson, but before long, the Hulk overpowered Moonstone, exposing her identity of Dr. Karla Sofen.[7]

She was held at Project Pegasus for study. During a diversion elsewhere within Project Pegasus, another prisoner, Blackout, managed to escape his containment cell and free several of his fellow superhuman criminals, including Moonstone, who were also there to be studied. Blackout and his new ally, Moonstone, escaped the confines of Pegasus, but were later tracked down by the Avengers.

Attempting to escape from them, Blackout opened up another aperture into the "dark dimension", and he and Moonstone were sucked into that dimension. (Note: the so-called "dark dimension" from which Blackout drew Darkforce is not to be confused with the Dark Dimension previously ruled by Dormammu and now the domain of Clea).

Moonstone used her energy powers to ascertain where they were and helped Blackout navigate them out of the Darkforce dimension to the Earth's moon. Moonstone hoped to augment her superhuman powers on the Moon's surface, but before she could do so, members of the Moon's resident race, theInhumans, aided by the mutant Dazzler, overpowered the two escaped criminals. Blackout and Moonstone were taken back to Earth and were returned to captivity at Project: Pegasus.[8]  Years later, Dr. Sofen joined the Masters of Evil.[9]  She was a part of the group that participated in the infamous siege on Avengers Mansion.[10] Karla as Meteorite

Thunderbolts
When most of the worlds heroes disappeared after the Onslaught crisis, Sofen again teamed with Baron Zemo. Under the guise of Meteorite, she was a founding member of the Thunderbolts, a team of super-villains masquerading as heroes to gain the trust of the people long enough for Zemo to steal sensitive SHIELD files. Eventually their cover was broken, but Karla joined most of her teammates in sustaining the Thunderbolts as a true superhero team.

With the aid of Hawkeye, the Thunderbolts came to be viewed as true heroes. Karla was pardoned for her past crimes, but was soon drawn back into the heroic life. On Counter-Earth, she obtained another Moonstone through deception. She also became romantically involved with Hawkeye.

Her increased powers and instability began to worry the other members. Graviton also began confronting her. While the two demonstrated their power, Graviton secretly levitated a pebble and used it to murder one of Karla's childhood friends. Karla's discovery of this seemed to drive her mad. During a battle between the Avengers and Thunderbolts, Hawkeye was forced to use a special arrow to inhibit her intangibility long enough for Vision to remove her moonstones.

Sofen was left comatose after these events and Baron Zemo gained control of the moonstones. From that point on, he manipulated her to do his bidding for him; her mind however, was still not functional. This changed after Songbird sent Zemo into a whirlwind of cosmic time/space releasing Sofen from his control. Her body was retrieved by the Commission on Superhuman Activities and remained in one of their facilities. Songbird was mentally linked through the moonstones' power when betraying Zemo. Karla and her teammate came out of their individual comas, with Karla mentally stable and her powers under control with one of the moonstones in her possession again.

Sofen became the field leader of Norman Osborn's Thunderbolts sponsored the U.S. Government in conclusion of the Superhuman Civil War. Although she was initially uninterested, a blackmail from Norman Osborn threatening to surgically remove her moonstone from her body left her with little choice because the action would leave her comatose. Although she served her function on the team, she proved less-than effective as the team leader (she tried to rush through the Thunderbolts first mission to have sexual intercourse with one of the dock workers at Thunderbolts Mountain).

Moonstone was among four Thunderbolts members present during an attack on Thunderbolts Mountain by a renegade Skrull sleeper agent Khn'nr who had taken the form of Captain Marvel but had refused to follow his programming and had pledged to defend the human race.[11]  During the battle, Khn'nr revealed that her stone was of Kree origin, and used his energy-controlling abilities to shut it down.[12]  Later, Bullseye tried to kill Songbird under Osborn's orders. Songbird managed to get into the Zeus aircraft, and blew up part of the Thunderbolts' mountain headquarters. Moonstone survived because Bullseye had warned her to go intangible, and walked away from the team.[13]

Dark Avengers
Norman Osborn gave her a spot on the Dark Avengers. She was given the codename and original costume (reclaimed from Ultra Girl) of Ms. Marvel after Carol Danvers had refused to follow Osborn.[14]  On the Dark Avengers' first mission, the new Ms. Marvel attacked Morgan le Fay by blasting her off her dragon, causing her to die in the present.[15] Karla as Ms. Marvel Osborn forced all of the Dark Avengers to undergo Psych Evaluations. After going through some of Karla's memories psychically, Dr. Gerald Wright discovered the memories of her mother's death were locked behind a "Hulk shaped door". He had come to kill the Dark Avengers because they were all made up of criminals, and he made Karla begin choke herself to death. As Karla was choking herself, she tricked him by getting him to go back into her head where she revealed she had killed her mother and hated being seen as a criminal and a failure. After Karla broke free, she asked him if he was prepared to do what she did and shot his right arm off and possibly choked him to death.[16]

After being told by Norman Osborn to find A.I.M., Karla sorted through the original Ms. Marvel's A.I.M. leads and took out an A.I.M. cell in Atlanta,Georgia. There she found baby M.O.D.O.C.'s, enhanced to warp reality. They communicated with her telepathically, telling her that they need Ms. Marvel to save them. It was unclear if they are controlling her, or if she genuinely cared about them, but Karla took them back to her room in theAvengers Tower for safe keeping. Almost immediately her room was blown apart by a strange yellow being.[17] With the aid of Venom, Noh-Varr and Iron Patriot, Karla managed to defeat the mysterious being and after a meeting with the Dark Avengers, the babies were moved to Thunderbolt's Mountain where they were stolen byDeadpool on behalf of A.I.M.[18]

Later while flying through the city, Karla came across a green version of Ms. Marvel's lightning bolt on the side of a building. Karla went back to the Avengers Tower where Osborn informed her Deadpool stole the baby M.O.D.O.C.s. Karla confronted him in Los Angeles. After defeating him, Karla came across the New Avengersand four of the mysterious beings, each one a different color, in an underground A.I.M. base. Trying to save the babies, Karla was too late to reach them as Spider-Man hooked them up to a machine. The four mysterious beings then merged and reform Carol Danvers, the original Ms. Marvel.<sup class="reference" id="cite_ref-Ms._Marvel_Vol_2_41_18-0">[19]  Refusing to let her title be taken away, Karla attempted to pound Danvers, but strangely, no matter what she hit her with, Danvers survived each and every blow.<sup class="reference" id="cite_ref-Ms._Marvel_Vol_2_42_19-0">[20]  Eventually, it was discovered that Danvers had a counterpart named Catherine Donovan, who, in close proximity, allowed Danvers to be invulnerable.

It is shown that, at some point, Karla start to feel very attracted to Daken. It didn't take long to the two start flirting among themselves and something more sparked in Karla. As a M.D. in psychiatry, Karla start to get fascinated with the mysterious, brilliant and terrible personality of Daken and how she can't predict what he gonna do next <sup class="reference" id="cite_ref-Dark_Wolverine_.2381_20-0">[21]. Karla demonstrated romantic feelings for Daken, but after a conversation with the mutant, Sofen realize that Daken is a liar and their relationship and the relation of Daken with the Dark Avengers was nothing but a way Daken used to have fun and achieve his goals. Still interested in Daken but disillusioned, the intimacy of the two turned cold at this point.

Karla was sent out by Osborn to help quell the riots in San Francisco along with the other Dark Avengers andH.A.M.M.E.R. Outside the Castro Theatre, she took out Nekra and Frenzy much to the surprise of Karma,Armor, and Bling.<sup class="reference" id="cite_ref-Dark_Avengers_.2F_Uncanny_X-Men:_Utopia_.231_21-0">[22]  Later she came into conflict with Rogue, accusing her of attacking an unconscious H.A.M.M.E.R. agent and viciously attacked her, though Rogue managed to trick her and escape.<sup class="reference" id="cite_ref-X-Men:_Legacy_.23226_22-0">[23]

Siege
Prior to the Siege of Asgard; Moonstone was flirting with Bullseye.<sup class="reference" id="cite_ref-Dark_Avengers_.2310_23-0">[24]  Karla is caught having sex with Bullseye in the Avengers Tower meeting room in front of H.A.M.M.E.R agents as Victoria Hand and Norman Osborn watch on a security camera. This act was perceived as an act of rebellion from Karla against Norman Osborn's rule over the Dark Avengers. Norman sends Victoria Hand to deal with the situation. Hand confronted Moonstone and Bullseye with a group of H.A.M.M.E.R agents. Moonstone disobeyed Hand's orders, which prompts Hand to take out an alien weapon to shoot Moonstone, knocking her unconscious.<sup class="reference" id="cite_ref-Dark_Avengers_.2314_24-0">[25]  Moonstone was later approached by Venom who told Karla that he had been waking up 'sticky' after dreams and was wondering if she could help him. At first she looks disgusted at Mac Gargan's attempts to approach her. While this is happening, Daken walked up to her and called her 'sweetheart'. Karla wrapped her arm around Venom's arm and spurns Daken in the process.<sup class="reference" id="cite_ref-Dark_Wolverine_.2315_25-0">[26]

During the Siege of Asgard, Moonstone was seen helping Osborn defeat Thor.<sup class="reference" id="cite_ref-Siege_.231_26-0">[27]  She was seen being chased away by Maria Hill, turning intangible to avoid the shots fired at her. Moonstone was one of the on-lookers when Sentry tore Ares in half.<sup class="reference" id="cite_ref-Siege_.232_27-0">[28]  She was standing beside Norman Osborn when the New Avengers, Young Avengers, and Nick Fury led by Steve Rogers arrived to assist the Asgardians. Captain America hit Osborn with his shield as Karla retreated, prompting her to say "Well, I sure as @#$% saw this coming!" as she engaged in personal combat with Ms. Marvel (Carol Danvers). Karla won the exchange when Osborn interfered with the fight by blasting Ms. Marvel with an energy beam. When Osborn reverted back to his Green Goblin persona after being defeated by Iron Man (Tony Stark) and Captain America, Karla and Bullseye are seen in the distance. Both of them come to the realization that it would be a good time to leave the battle.<sup class="reference" id="cite_ref-Siege_.233_28-0">[29]

Moonstone, along with the other members of the Dark Avengers, was arrested by the Avengers. After Captain America does away with Norman Osborn, Moonstone and Bullseye took the opportunity to attempt an escape. Carol Danvers gave chase to Moonstone, only to have Karla fire on her with an energy blast. When it seemed she had escaped, Iron Man appeared and punched her, knocking her out. At the same time, Bullseye was struck down by Luke Cage, sending the two villains falling unconscious to the ground, thus ending Moonstone's career as an "Avenger". ===Heroic Age=== Imprisoned on the superhuman prison known as the Raft, Moonstone was one of the initial recruits selected for a new Thunderbolts program led by Luke Cage.<sup class="reference" id="cite_ref-Thunderbolts_.23144_29-0">[30]  Man-Thing took a liking to her.
