Hive

Hive is an ancient, parasitic Inhuman banished to a desolate alien world centuries earlier, brought home at last by generations of Hydra sacrifices. It takes over Grant Ward's corpse to build a following and spread a mind-control pathogen, before being destroyed in orbit when Lincoln Campbell detonates the warhead meant to carry it.

First turns up in Agents of S.H.I.E.L.D. (Season 3).
