Marvel Knights: Inhumans.

The Inhumans have always been one of Marvel's most enduring oddities. A race of genetic outsiders, they live secluded in their island kingdom of Attilan, preferring not to mix with the outside world. Even stranger, their genetic mutations are self-endowed; each Inhuman, as a coming-of-age ritual, endures exposure to the Terrigen Mists, a strange substance that imparts unearthly powers--some extraordinary, some monstrous.
