Karla Sofen, later known as Moonstone and publicly rebranded as Meteorite, was once a highly respected psychiatrist whose career focused on the study of superhumans. Her life was irrevocably altered when she was chosen by the Kree to become the bearer of the Moonstone, a powerful artifact designed to replicate the abilities of Mar-Vell. What began as a covert mission to capture Carol Danvers evolved into a dangerous obsession that consumed every aspect of Karla's identity. Torn between hatred, admiration, desire, and envy, Karla's fixation on Carol ultimately became the defining force of her life. Though she now presents herself as one of America's newest heroes, beneath the heroic image remains a manipulative woman determined to ensure that neither she nor her fellow reformed criminals ever forget who they truly are.
Before becoming Moonstone, Karla Sofen was a renowned psychiatrist. She earned recognition and awards for her work studying superhumans and their psychological conditions, establishing herself as one of the most respected professionals in her field.
Everything changed following her abduction by an ancient extraterrestrial civilization.
The beings responsible identified themselves as the Kree, a mysterious race distinguished by their bluish skin and flowing hair. The Kree had recently created a powerful artifact known as the Moonstone, designed as a vessel capable of replicating the abilities once possessed by Mar-Vell.
The creation of the artifact was made possible through extensive research conducted on Carol Danvers, whose own powers originated from Mar-Vell and had remained under Kree control for a period of time. Seeking to regain influence over those abilities, the Kree selected Karla for a specific purpose.
She would become their infiltrator.
The Kree bonded Karla to the Moonstone and entrusted her with a mission: infiltrate Carol Danvers' life, gain her trust, and ultimately capture her. Armed with immense power and a purpose engraved into her mind, Karla returned to Earth transformed.
At first, she used her newfound abilities largely for her own benefit. Yet despite pursuing her personal ambitions, she never truly escaped the mission planted within her consciousness. Over time, that purpose evolved into something far more dangerous.
What began as an assignment developed into a profound psychological obsession with Carol Danvers.
Karla first approached Carol as a friend. Later, she became her therapist. Eventually, she became her lover. Through each stage of the relationship, Karla sought to move closer to Carol, gradually attempting to take possession of her life and identity.
The obsession fed an increasingly severe psychosis. Carol became the center of Karla's emotional world—someone she wanted to defeat, control, possess, torment, and love all at once.
This destructive relationship ultimately reached a turning point when Moonstone attempted to help free members of the Masters imprisoned within the Raft. During the operation, she was confronted and captured by Major Marvel, bringing her plans to an abrupt end.
Yet imprisonment and separation changed nothing.
Years passed without Karla seeing Carol, but not a single day went by in which she failed to think about her. Her obsession endured, remaining as powerful as ever despite the distance between them.
In the present day, Karla operates under the heroic identity of Meteorite, serving as Florida's representative among America's government-sponsored superhuman heroes.
To the public, Meteorite appears to be a success story: a former criminal who has embraced heroism and become one of the faces of a new generation. She regularly appears on magazine covers alongside Atlas, Texas' champion, helping present the image of redeemed villains serving their country.
Privately, however, Karla rejects the very idea that she or her fellow teammates have truly changed.
Unlike some members of the program, who have begun to embrace their heroic identities and seek redemption, Karla views such developments with disgust. She remains determined to ensure that those around her never forget their criminal origins or the people they once were.
To achieve this, she carefully manipulates both allies and enemies alike, engaging in what she considers a delicate and complex psychological game. Through calculated actions, she continually reminds others of their pasts and challenges the legitimacy of the heroic personas they have adopted.
One of the clearest examples of this occurred after Songbird publicly recounted a revised version of her origins during an interview with the Daily Bugle, presenting herself as a scholarship student from a private school in Los Angeles. Interpreting the story as an attempt to erase the truth, Karla took matters into her own hands.
She tracked down the Grapplers, the women who had raised Melissa Gold after she ran away from home, and annihilated them using her powers. She deliberately left evidence behind as a reminder—not only for Songbird, but for everyone involved—that the past cannot be rewritten and that their true origins can never be escaped.
Today, Karla Sofen remains one of the most dangerous and psychologically complex members of America's new heroic initiative. Beneath the identity of Meteorite still exists Moonstone: a woman driven by obsession, manipulation, and an unwavering refusal to let either herself or those around her forget who they truly are.
