I am Ronan the Accuser. Wherever I set my foot, there Kree law holds sway.
~ Ronan introducing himself
Captain Marvel... I accuse you of being out of date. Of being a festering relic, an unpleasant memory. A mere half-Kree you may be, but what you symbolize is a full-blooded embarrassment. We shall have to do something about you. For that is the rule of law... --and the law of Ruul.
~ Ronan the Accuser to Captain Marvel.
Ronan the Accuser is a villain-turned-anti-hero from Marvel Comics and the on and off antagonist of the Guardians of the Galaxy team as well as an enemy of various superheroes in the Marvel universe, including the Fantastic Four. He is the leader of the accuser corps, the elite military police of the Kree Empire.
He was born into one of the leading Kree aristocratic families on Hala. After completing his education he was accepted into the ranks of the Accuser Corps, where he quickly rose through the ranks. Eventually, he was promoted by the Supreme Intelligence to the rank of Supreme Public Accuser. One of Ronan's missions was to punish the Fantastic Four when they defeated a Sentry left on Earth. But when he traveled to Earth and faced the four heroes, he was soon forced to use his own weapon on himself, giving himself the same sentence that he intended to mete out upon them. Unable to seek revenge due to the Supremor's orders, Ronan joined with Imperial Minister Zarek to depose the Supremor but was defeated by the Avengers.
Later Ronan made another attack against the Four when he attempted to gain possession of a Universal Power Core from Uatu The Watcher's house. With the aid of a mind-controlled Invisible Woman, he was able to breach the dome but was only able to obtain the plans to one of them.
After a failed attempt to absorb Ego into himself, Ronan returned to his post as the Supreme Public Accuser and is helping the Supremor evolve those Kree who were able to avoid being turned into Ruul.
When Ronan is falsely accused of treason by Tana Nile, he discovers he has been framed by a highly placed member of a Kree house. After defending the Kree Empire against the Annihilation Wave, Ronan clears his name and kills his betrayer, although not before he lobotomizes the Supreme Intelligence. In an act of mercy, Ronan kills the Supreme Intelligence and becomes ruler of the Kree Empire.
During the Phalanx conquest of the Kree, Ronan works with the Super-Skrull and Wraith to free his people.
When the Inhumans seek aid from the Kree against the Skrull's Secret Invasion, Ronan agrees on the condition that the Inhuman princess, Crystal, marries him. On their wedding day, Ronan is severely beaten by the Shi'ar Imperial Guard and hospitalized. He does not fully recover until after the War of Kings is over.
Ronan is soon separated from his wife under the orders of Black Bolt, as part of a truce made between Black Bolt and the Supreme Intelligence to ensure peace between Inhumans and the Kree Empire. Crystal and Ronan are deeply saddened by this decision, as their arranged marriage had eventually become a stronger relationship.
During the Infinity storyline by Jonathan Hickman, Ronan, along with the other members of the Annihilators and their respective races, helped the Avengers fighting the Builders.
Ronan the Accuser steals The Black Vortex from the cosmically powered X-Men, and, against the Supreme Intelligence's orders, submits to the Vortex and receives cosmic powers. Mister Knife later steals the Vortex and destroys Hala and the Supreme Intelligence. Ronan and the imperial fleet survive, but the last remaining seed of the Supreme Intelligence was stolen from the Collector by Star-Lord's half-sister Victoria.
Ronan wanders the ruins of Hala alone while remembering the names of the Kree that fell in battle when he came into conflict with Noh-Varr and the Inhumans except for Crystal. Thanks to Crystal's reasoning, Ronan blames himself for disobeying the Supreme Intelligence's orders. After freeing his captive, Ronan witnesses Noh-Varr planting the seed of his reality's Plex Intelligence into the remains of the Supreme Intelligence. Even though Hala has a new leader, Ronan still blames himself for what happened to the planet and his people.
In the pages of the "Death of the Inhumans" miniseries, Karnak confronts the unnamed commander of a Kree contingency that was sent away to explore and chart the outer reaches of the Universe a long time ago. After generations away they finally returned to Hala, only to find it in ruins. The Kree commander also reveals that they eliminated Ronan, exile those loyal to him and decided use the Inhumans as part of their plans to rebuild Hala and bring a new dawn to the Kree Empire. However, Black Bolt eventually found out that the Kree commander had lied to Karnak about Ronan's fate. The Kree actually captured him and the Kree soldiers loyal to him and made gruesome experiments on them. Now merely a cyborg, Ronan begged Black Bolt to end his misery as he apologized for all the pain he caused to the Inhumans to which he complies by whispering "You are forgiven."
