Arkea is a sentient bacterium born over a billion years ago as one of the first forms of life on Earth alongside her brother, Sublime. Eons ago, the two engaged in a microscopic battle to decide who would inherit the planet and dictate the flow of life, with her sibling emerging victorious. Cast out into the abyss, she traveled to alien worlds and evolved separately over the coming millennia.
Eventually, she returned to Earth in modern times by riding a series of meteors, intent on exacting revenge on her brother and claiming her birthright. To this end, she used her technopathy to possess the body of Omega Sentinel.[1] Upon her awakening Arkea/Karima opened an uplink to the Jean Grey School's vast A.I. database for her own primordial purpose of contagious planetary conquest and revenge against her brother, who just so happened to have given himself up to the X-Men for protection against her.
