Unspoken

The Unspoken is a supervillain appearing in American comic books published by Marvel Comics. He is the cousin of Blackagar Boltagon (Black Bolt), and was once the king of the Inhumans before he was forced into exile. The Unspoken first appeared in The Mighty Avengers #27 and was created by Dan Slott, Khoi Pham, and Christos Gage.

Originally, the Unspoken was a just ruler to the Inhumans. However, fearful that it would corrupt his people, he stole the Slave Engine, his people's greatest weapon, along with the Xerogen Crystals it utilized and buried them somewhere in Tibet. After refusing to reveal the Slave Engine's location, he was challenged to a duel by the heir to the throne, a young Blackagar Boltagon. Despite being the strongest of the Inhumans, moving the Slave Engine had weakened the King which led to his defeat at the hands of Blackagar and his friends. His final stipulation was that his deeds be remembered, but Black Bolt had a crueler fate in mind: the King, his deeds, and the Slave Engine itself, were written out of Inhuman history. From that day on, he would be remembered only as a Bogeyman to frighten small children, his name left "unspoken".

The Unspoken is recovered by the Alpha Primitives, who care for their fallen king. Realizing his mistake, the Unspoken plots to return and reclaim his throne, cultivating the Xerogen Crystals, only for Attilan to rise into the sky. Cheated of his redemption and later learning of the silent war between the Inhumans and United States of America, the Unspoken decides to change his plans and unearth the Slave Engine using it to conquer Earth, by transforming all humans into Alpha Primitives.The Mighty Avengers #27 (September 2009) The Unspoken is defeated when the chronal ray on board the Slave Engine that accelerated the growth of the Xerogen crystals is used against him, aging him to the point where he is too weak to carry on fighting.The Mighty Avengers #31 (January 2010)

The Unspoken is the living embodiment of Terrigenesis itself. He is capable of altering his form in any way he desires, and can give himself a wide number of abilities, such as mass manipulation and energy construct manifestation. To maintain his powers, he needs to absorb Terrigen Crystals.
