Yon-Rogg[1] is a Kree military officer from the planet Hala. As a Colonel in the Imperial Kree Army, he has long served the interests of the Kree Empire, often through covert or aggressive measures.[2] His career became deeply intertwined with that of the younger soldier Mar-Vell, whose idealism and combat skill sparked Yon-Rogg's enduring jealousy—particularly after the ship's medic, Una, grew affectionate toward Mar-Vell.[3] Their early mission into the Brood galaxy brought them into conflict with the Skrulls, the Shi'ar, and the monstrous Brood, with Yon-Rogg emerging from the ordeal with command of the Kree vessel, the Helion.[4]
Yon-Rogg's rivalry with Mar-Vell deepened during their deployment to Earth. Tasked with investigating how a Kree Sentries was destroyed by primitive Earthlings, Rogg manipulated Mar-Vell into solo missions in hopes he would be killed.[5] Failing that, he reactivated the Sentry himself to eliminate Mar-Vell and later involved the Super-Skrull in his schemes.[6] When Ronan the Accuser ordered Mar-Vell's execution, Yon-Rogg was eager to obey, but the mission was disrupted by an Aakon attack that claimed Una's life.[7] Yon-Rogg later revealed his role in a larger conspiracy alongside Zarek to overthrow the Supreme Intelligence.[8]
Ultimately, Yon-Rogg abducted Carol Danvers to use against Mar-Vell. Their confrontation ended with an explosion from the Psyche-Magnitron, apparently killing Yon-Rogg and altering Danvers at the genetic level, giving her a human-Kree hybrid physiology.[9] Years later, Yon-Rogg resurfaced as Magnitron, empowered by the same device that had once irradiated Carol.[10] Using Carol's memories against her, Magnitron launched a psychic assault and attempted to destroy New York by dropping a Kree city upon it. In the process of stopping him, Carol suffered brain trauma that erased her memories.[11]
History
Early Life[]
Yon-Rogg is a Kree hailing from the planet Hala in the Large Magellanic Cloud. He is a Colonel in the Imperial Kree Army which protects the interests of the galactic Kree Empire.[2]
Mission to the Brood Galaxy[]
Yon-Rogg was second in command of the Pama under the command of Zen-Pram. They were sent on a mission to find famous Kree military hero Devros who disappeared into the deadly Brood galaxy. On the mission he is teamed up with a young, idealistic soldier named Mar-Vell. Yon-Rogg's jealousy of Mar-Vell began on the mission when Una the ships medic had an instant crush on Mar-Vell. The mission lead them into conflict with both the Skrulls and the Shi'ar.[3] He helped Mar-Vell battle Deathbird and the Imperial Guard.[12] They sent Mar-Vell down to the planet only to find Devros had been captured, turned into a Brood, and that Mar-Vell killed him and escaped from the world. Yon-Rogg was then given his own command over the Kree Ship; Helion.[4]
Mission to Earth[]
Yon-Rogg was sent on a mission to the backwater planet called Earth by the Supreme Intelligence. They were sent to investigate how the primitive natives had taken down a Kree Sentry. When they arrived at Earth; Yon-Rogg sent Mar-Vell on the lone mission to the planet with hopes he would die whilst on the primitive planet.[5]
Yon-Rogg's annoyance with Mar-Vell only grew his hatred for him and actively tried to get him killed on their mission to Earth. Also, he was deeply jealous of the relationship between Mar-Vell and the medic Una.[13]

Yon-Rogg managed to get access to the Sentry and reactivate it. He hoped the Sentry would fight and destroy Mar-Vell, but he failed.[14] With that failure he hoped a battle with the Super-Skrull would do the job for him and he could return home.[15]
When Ronan the Accuser ordered Mar-Vell's execution, Yon-Rogg was only too happy to comply.[16] However, when Mar-Vell was before the firing squad, they were attacked by a contingent of Aakon warriors. In the battle, Una was fatally wounded by a stray shot by an Aakon. Mar-Vell escaped on an Earth missile and laid Una's corpse to rest on an asteroid. Yon-Rogg seized Mar-Vell's missile with a tractor beam and hurled it into hyperspace.[17]
Yon-Rogg confronted Mar-Vell aboard the Kree Ship as it was restocking.[18]It was later revealed that Ronan and Zarek arranged for Mar-Vell to work under Yon-Rogg as part of a plan to topple the Supreme Intelligence so Ronan and Zarek could replace the Supreme Intelligence as rulers of the Kree Empire.[8]
Yon-Rogg battled a young human; Rick Jones who used Mar-Vell's Nega-Bands to defeat the Kree commander.[19] Yon-Rogg then kidnapped Carol Danvers as a hostage to use against him. Yon-Rogg was defeated by Mar-Vell, and apparently died when a nearby Kree device exploded. In the course of this battle Danvers was irradiated by a Kree Psyche-Magnitron, causing her to develop a half-Kree physiology which was similar to Mar-Vell's.[9]
Magnitron[]
Yon-Rogg survived the Psyche-Magnitron explosion, gaining enhanced powers similar to Carol Danvers. He tried to regain favor with the empire by stealing back the Psyche-Magnitron device but they declined his offer. Now known as "Magnitron," he used Carol's memories to torture her with enemies from her past. He then attempted to drop a Kree city on top of New York City. Carol however managed to disconnect the telepathic link only to make the lesion in her head to burst, causing her to lose all her memories.[10][11]Attributes
