The Assassination of Norex was an attempt to eliminate Vers, undertaken by Yon-Rogg.
Background[]
The Kree waged war on the Skrulls and falsely claimed that they were heartless monsters who used their disguise abilities to infiltrate and collapse civilizations. The Kree obliterated Skrulls' forces across the galaxy and even destroyed their home planet.
The Skrulls allied themselves with Mar-Vell, a Kree scientist who discovered the lies of the Kree Empire. Mar-Vell was building a Light-Speed Engine which would help the Skrulls to find a new planet to live in. However, in 1989 she was murdered by the Starforce and the energy that powered the engine was absorbed by Carol Danvers who got cosmic powers.
Danvers was taken by the Starforce leader Yon-Rogg hoping to brainwash her and user her powers against the many races the Kree fought against. In 1995, Danvers, nicknamed Vers, learned of the truth and decided to help the Skrulls led by Talos. Meanwhile, Yon-Rogg tracked Vers' beacon to a shack on Planet C-53, where she was believed to have been captured by the Skrulls.[1]
Assassination[]
Norex disguises as Vers
Yon-Rogg found Vers in a shack, where she tried to use the Kree's code system to identify herself to him. He stopped her, noting that the code system was compromised. They then began asking each other questions that they thought a Skrull wouldn't be able to answer. When Yon-Rogg asked her about her earliest memory of Hala, she correctly answered that it was a transfusion, with blue blood running through her veins, but when he asked her whose blood it was, she was surprised, unable to answer. Yon-Rogg correctly deduced that it was a Skrull and shot him in the chest with his pistol, fatally wounding him.
In his final moments, Norex transformed back to his own Skrull shape. Yon-Rogg remarked to him that the blood coursing in her veins is his, and demanded to know what the Skrulls had done to her. Norex replied by saying that Yon-Rogg was too late, before an angered Yon-Rogg executed him with a final shot.[1]
Aftermath[]
Yon-Rogg calling for Ronan the Accuser's support
Learning that Vers was compromised and knew everything, Yon-Rogg contacted Ronan the Accuser, asking for his help to eradicate Skrulls from Earth. Yon-Rogg then tracked Vers to Mar-Vell's Laboratory, leading to a fight involving the Starforce, Accusers, Vers and her allies.[1]
