Publication history
Yon-Rogg first appeared in Marvel Super Heroes #12 (December 1967) and was created by Stan Lee and Gene Colan. He was introduced as a Kree commander sent to Earth to investigate how the planet's seemingly primitive inhabitants managed to destroy an advanced Kree Sentry. During this mission, he tried to kill Captain Marvel (Mar-Vell) out of jealousy and who was in a relationship with another Kree called Una. His schemes ended in Una dying, which resulted in animosity between the two.
Yon-Rogg later attempted to defeat his nemesis by kidnapping Carol Danvers and using her as a hostage. He was seemingly killed when a Kree device, a Psyche-Magnitron, exploded. That same explosion also awoke Carol's latent genetic potential, transforming her into the superhero Ms. Marvel. He returned years later as Magnitron, to enact revenge on Carol, who then known as Captain Marvel. Yon-Rogg attempted to telepathically torture Carol and destroy New York City. He was defeated once again, although it cost Carol her memories.
Fictional character biography
Yon-Rogg is a Kree military officer who is the commander of the Helion, a Kree spaceship that was sent to Earth by the Supreme Intelligence. Yon-Rogg had a deep hatred towards Mar-Vell due to his love for the Kree medic Una. He ends up leaving Mar-Vell on Earth so that Una can be his. Yon-Rogg later unleashes the Kree Sentry to dispose of Mar-Vell. During his fight with the Sentry, Mar-Vell learned that the Sentry attacking him was sent by Yon-Rogg. After Mar-Vell defeats the Kree Sentry, Yon-Rogg contacts Ronan the Accuser to pass judgement on Mar-Vell's actions. Ronan declines the offer stating that the mission was not jeopardized by Mar-Vell's actions.
Yon-Rogg was on his spaceship at the time when Mar-Vell was fighting Super-Skrull and hopes that Super-Skrull would kill Mar-Vell. After Mar-Vell breaks free from Super-Skrull's ship, Yon-Rogg refuses Mar-Vell's offer to return to Earth so that he can stop Super-Skrull.
Yon-Rogg later sabotages a rocket carrying deadly bacteria that was bound for space where it crashes into the ocean. When Mar-Vell arrives at the Cape, he is ordered by Yon-Rogg to prevent the humans from stopping the rocket from releasing the bacteria where Mar-Vell has his encounter with Namor.
Yon-Rogg has Mar-Vell put on trial for being "Un-Kree" by letting Namor beat him. Though Ronan the Accuser has Mar-Vell take out Mr. Logan upon him finding out his identity before a device Mar-Vell had ended up putting Mr. Logan into a coma.
During Mar-Vell's holographic training program, Yon-Rogg cranks up the setting hoping that Mar-Vell would die from the experience. Following Mar-Vell's fight with Solam, Yon-Rogg plans to put Mar-Vell on trial before Ronan the Accuser again.
Yon-Rogg then plans to kill Mar-Vell's fellow cape member Carol Danvers with Kree weapons with Mar-Vell saving her. Yon-Rogg plotted to use this to invoke jealousy in Una. After Mar-Vell had defeated Quasimodo, Yon-Rogg continues to make Una jealous of Mar-Vell and Carol's relationship.
When an Aakon spaceship approaches Earth, Yon-Rogg orders the Kree to attack the spaceship since the Kree have been age-old enemies of the Aakon race. During their fight on the moon, Yon-Rogg is injured and Mar-Vell had to kill the Aakok spaceship's leader to protect Yon-Rogg. While Yon-Rogg is recuperating, Mar-Vell assumes control of the Kree ship.
When Mar-Vell starts to develop a friendship with Carol Danvers, Ronan the Accuser orders Yon-Rogg to lead some Kree soldiers into executing Mar-Vell. Yon-Rogg is happy to oblige. After Una dies from her injuries upon being caught in the crossfire between the Kree and the Aakons, Zo frees Mar-Vell from the control bands that Yon-Rogg put on him, and has Mar-Vell go after Yon-Rogg for revenge upon bestowing new powers onto him. Mar-Vell uses his illusion casting to taunt Yon-Rogg into thinking that he is alive. While a supply ship is restocking the Kree ship, Mar-Vell ends having a brief fight with Yon-Rogg before returning to Earth to save Carol Danvers from Man-Slayer.
