Zarek, a member of the Kree race, possesses enhanced strength, stamina, and durability due to his blue Kree heritage. Leading the Lunatic Legion, he hatched schemes alongside Ronan the Accuser, aiming to overthrow the Supreme Intelligence. Zarek's ideology of blue Kree supremacy clashed with his racist views, leading to conflicts with the Shi’ar, the Brood, and the Fantastic Four. Once Imperial Minister, Zarek conspired to brand Captain Marvel as a traitor, but Mar-Vell's loyalty to Earth foiled their plans. The Supreme Intelligence thwarted Zarek's assassination attempt, leading to Mar-Vell's heroic sacrifice. Zarek fled into exile and established the Lunatic Legion on the moon, seeking blue Kree dominance. The Legion's defeat and Uatu's trial exposed Zarek's failure. During the War of Kings, Zarek's whereabouts remained unknown. In a post-war era, he and Doctor Vere plotted to restore the original Kree Houses using manipulated Alpha Primitives. Zarek's intricate past, marked by conspiracies and conflicts, reflects the complexities of Kree politics and his relentless pursuit of supremacy.
