Moonstone

Karla Sofen was a renowned psychiatrist, who enjoyed manipulating her patients into paranoia rather than helping them. Her unethical behavior led her to be an assistant to the villainous Doctor Faustus, who improved her manipulative skills. This allowed her to pave her way to Lloyd Bloch, the powerhouse villain known as Moonstone. Drugging Lloyd with hallucinogens, Sofen persuaded him into giving her the Moonstone, the Kree device that granted him immense powers. As the new Moonstone, Sofen became a prominent super-criminal, being recruited into Baron Zemo's Masters of Evil and facing the Avengers on several occasions.

She's also played the role of anti heroine.

Enemy of Captain Marvel.

Powers Karla's powers are the result of her fusion with a gravity stone designed by the alien Kree. After being absorbed into her body, the stone took on the form of energy that permeates her nervous system. Karla once acquired a second gravity stone, increasing her powers to new limits. However, she currently only possesses one stone and her abilities have reverted to their old levels.[citation needed]

Superhuman Strength: Karla possesses superhuman strength sufficient enough to lift around 10 tons. Her strength allows her to perform incredible feats like ripping off the jaw of a dragon and then flipping the dragon itself to crush her enemies. Superhuman Speed: Karla is capable of running and moving at speeds that are beyond the natural physical limits of the finest human athlete. Superhuman Stamina: Karla's musculature produces considerably less fatigue toxins during physical activity than the musculature of an ordinary human. She can physically exert herself at peak capacity for about 24 hours before fatigue begins to impair her. Superhuman Durability: Karla's bodily tissues are tougher and more resistant to certain forms of physical injury than those of a normal human. She is able to withstand great impact forces, such as being repeatedly struck with superhuman force, powerful energy blasts or falls from great heights, that would severely injure or kill an ordinary human though she would suffer little to no injury herself. However, she is as vulnerable to conventional ballistic and bladed weaponry as any ordinary human. She has survived multiple blows from a powerful gamma-enhanced individual like Doc Samson and a blast from Penance that projected her through at least two walls but ended up in the hospital for weeks. It seems that her durability increased through the years as she survived a point-blank gunshot to the face without damage and a blast of Hyperion's atomic vision with just some pain. Superhuman Agility: Karla's agility, balance, and bodily coordination are enhanced to levels that are beyond the natural physical limits of even the finest human athlete. Superhuman Reflexes: Her reflexes are heightened in a similar manner and are superior to those of the finest human athlete. Gravitational Flight: Karla could also allow the Earth's gravitational pull to propel her through the air at a speed of roughly 500 mph. To the casual viewer this would make her appear to disappear or teleport. Minor Molecular Control: She can instantaneously change into/alter her costume. Shape-Shifting: As an extension of this ability she can take the appearance of another person. She first displayed this ability when under the control of an alternate Doctor Strange she took the form of Captain Marvel. Intangibility: She can make herself and other persons intangible by altering her or the person's synchronization of their body's density. Light Generation: She can generate a blinding luminescence from every inch of her body to blind her opponents. Energy Projection: She can shoot laser-like blasts from her hands that are powerful enough to penetrate a two-inch steel plate in 0.1 seconds when in a narrow beam and generate a concussive force equivalent to 100 pounds of TNT when in a wide beam. She has also displayed the ability to shoot her energy blasts from her eyes. Her energy blast have proved to be powerful enough to cause heavy damage even to the likes of Danger and set Skaar on fire.

Abilities: Expert Psychologist: Sofen is a trained psychiatrist.

Expert Hypnotist: She is particularly skilled in using hypnosis. Like her predecessor, Doctor Faustus, Moonstone has perfect pitch and modulation in her voice, and was even able to use these talents to cause Thunderbolt Ross to suffer a complete nervous breakdown. Weaknesses: If the stone is removed from her body, Karla will die in 72 hours without its support.
