Ripley Ryan grew up in what appeared to be an abusive home, often hiding to avoid physical punishment at the hands of her mother. In her education, employment, and social life, she was victimized and seemingly bullied into the façade she had developed of being a polite, average girl, while hiding severe trauma that would come to a boil later in her life
Ripley Ryan became a reporter for the magazine, Ms., and was hired by Tony Stark to interview Captain Marvel, who wanted to rejoin the Avengers after she had come back from a sabbatical and needed to rebuild trust with the public.
When she met Carol for the first time to interview her, they were attacked by Nuclear Man, who managed to defeat both Captain Marvel and the Avengers long enough to kidnap Ryan and take her through a portal to nearby Roosevelt Island. Captain Marvel was the only hero able to follow, though Spider-Woman, Hazmat, and Echo were already there. Eventually, Carol was able to defeat Nuclear Man by forming an army of the female civilians and heroes he had captured. Ripley was a part of that fight, and the prisoners were able to return home.
At some point, Ripley found out about Minn-Erva's efforts to genetically engineer Humans into Human-Kree Hybrids. Ripley volunteered for the experiment to receive superpowers and was the only survivor of Minn-Erva's experiments.
Ripley had become a hybrid, but had no superpowers to speak of. Since Minn-Erva had promised superpowers, she decided to utilize those she had stolen from Carol back when she had unleashed a "Kraken" on New York City with a virus engineered from Kree Power Siphons in its blood. Carol defeated it, but was infected and the powers siphoned off were given to Ripley.
Minn-Erva wanted Carol to join the Kree Empire's fight against extinction, since Carol was half-Kree herself, so she staged a public relations stunt to turn the public against Carol, hoping when the time came that Carol would join her cause. At the the same time, Ripley appeared as Star, helping battle against an armada of "Kraken" attacking Manhattan. After the downed "Kraken" crashed into the East River, Star stood by as Danvers pulled one of the pilots, who happened to be a Kree, free from the wreckage.
Star asked Captain Marvel if Carol wanted her to take the pilot off her hands, but Danvers told her that wouldn't be necessary. When Carol tried to get some answers from the newly fashioned hero, Star told her she had to leave due to some occurrence taking place downtown. This led to Ripley becoming an up-and-coming superhero, quickly rising in popularity as Carol's popularity plummeted.
When Star found out Minn-Erva planned on recruiting Carol, she nearly killed Minn-Erva, and left the message "You're not as smart as you think you are." written in Minn-Erva's own blood.
Carol brought Minn-Erva to Stark Unlimited HQ for medical treatment, where she revealed her plan to Carol, causing Carol to confront Star in Times Square. The two fought, but Carol was quickly growing weaker from the Power Siphons. Running out of options, Carol ripped the device from her own chest, severing the connection to Star, causing both women to fall to Earth.
Carol was seriously injured, while Star seemed fine. Star revealed that she had infected all of New York City with the virus, declaring if she can't draw power from one large battery in Carol, she would draw from millions of tiny batteries in all the New Yorkers.
Carol defeated Star by ripping the device out of Ripley's chest as well, causing her to lose her powers. Star was sent to the Raft; however, it was revealed Ripley had merged with the Reality Stone and subsequently escaped from the prison.
Weeks after her escape, Ripley entered the Bar with No Name. Inside, she got into a fight with Titania, but lost due to her inexperience with the Reality Stone and was thrown out back. Outside, Ripley was knocked out by Loki.
Inside a warehouse, Loki attempted to remove the Reality Stone, but failed. He told Ripley he wasn't envious of her position, because of those who will come for Stones, but when Ripley questioned who that was, Loki simply told her it was a long list. Star thanked him for the information and attempted to destroy him with the Stone, though unbeknownst to her, she had only destroyed an illusion of the trickster.
Ripley proceeded to Alias Investigations and asked Jessica Jones for help. Jessica refused, stating she knew who Ripley was and what she tried to do to Captain Marvel. The two women fought, but their fight was interrupted by the Scarlet Witch, who told Ripley she needed to stop, because she was destroying reality.
Ripley herself seemed a polite, average, young woman; however, she was abused as a child by a female guardian for disobedience. She stated that all she cares about is her freedom, as a result of a long history of abuse in her personal history in her home life, school, and employment. This most likely contributed to her PTSD and her trauma that was further exacerbated by her experiences on Roosevelt Island.
As Star, she first appeared to be a hero, fighting crime and saving lives; however, this was a ruse and her true personality was revealed to be that of an apathetic, power-hungry psychopath who cared little for others and viewed them as tools to further her own agenda. Ripley believed saving people only made them weaker, and got in the way of them helping themselves.
It was later revealed that during the course of Captain Marvel's destructive battle with Nuclear Man's army, Ripley had gone through severe emotional trauma due to being dragged in to Captain Marvel's "violent life" due to her being "famous". Having completely shifted the blame on to Carol due to her being dragged into her "mess" and being subjected to being repeatedly caught into the destructive crossfire of the battles she and her "Super Powered Invulnerable" friends fought and her being kidnapped by misogynists and robots on the daily, leading to Ripley feeling incredibly vulnerable both physically and psychologically and leading her to suffer panic attacks akin to Post-Traumatic Stress Disorder due to her horrible experiences in Nuclear World.
It was also revealed the PTSD was further influenced by her death. When Ripley awoke on the Raft, she was disorientated inside a body bag. The coroner informed her that she had passed away en route to the operating table after Captain Marvel had dropped her off with the hole in her chest; however, Carol was not aware Ripley had died as a result of the removal of the Power Siphon.
As part of the Thunderbolts team, Star displays a more caring personality (and has notably reverted to her original costume), showing concern for her teammates, willing to go back and fight an entire horde of symbiotes to save Batroc, and even suggested helping the Defenders fight off a horde that attacked them while her teammates refused. It appears from this she may be more stable than previously shown, or rather, her malice to heroes is directed solely at Carol Danvers and not her allies. 
Powers and Abilities
After merging with the Reality Stone, Ripley now has the ability to alter reality to however she sees fit. Like the Wuxian Seed before her, Ripley can power-up into a red, lifelike aether with black tendrils around her lower body, smoke emerging from her head, and the star around the neck of her costume extending to her lower body.
After becoming half-Kree, Ripley showed no changes in strength or appearance, despite Kree usually being stronger and faster than the average human.
- In Captain Marvel (Vol. 10) #11, Captain Marvel punched a hole into Star's chest to remove the Power Siphon, which unbeknownst to Carol, wound up being fatal; however, during Ripley's recapitulatory nightmare in Star #1, the trauma in her dream was seemingly exaggerated, and the wound went all the way through her chest.
- Ripley is a fan of Katrina and the Waves. After stealing numerous dogs, she proceeds to take them on a walk with multiple speakers blasting their hit song 'Walking on Sunshine'.
