Cognetic

Cognetic is the story of a powerful psychic being that once controlled one-third of the world's population as a part of its hivemind, and his return to humanity in modern-day New York City.
It's also the story of a young woman, the assistant to the director of the FBI, who might be the only one who can save humanity, but at a terrible, terrible cost.
Collects the complete limited series by writer James Tynion IV (Detective Comics, The Woods) and artist Eryk Donovan (Memetic), plus character profiles, essays, sketches, and cover gallery.
