Ronan the Accuser (Earth-62015)

Ronan the Accuser is a fanatical member of the Kree race who had a strong sense of Kree justice. When the Kree scientist Mar-Vell defected to the Earth, and had unknowingly mated with the Eternal and Skrull races, Ronan made it his business to execute Vell and the planet he defected to: Earth. After an initial defeat where he fled, he returned. Wielding an Infinity Stone, he sought to destroy the Earth, but Mar-Vell's valor won out and Ronan was destroyed by the very power he wielded.
