Tucker Shockley

Origin
Trevor Shockley was a man in his apparent mid-fifties. He was a member of a group called the Watchdogs and worked for a Russian "superior" named Anton Ivanov. Ivanov was obsessed with cleansing the world of Inhumans, and believed that the path towards accomplishing this goal lied within the pages of the Darkhold.

Ivanov sent Shockley to U.S. senator Ellen Nadeer's office - an avid proponent of controlling the Inhuman population. They suspected that Nadeer might have possessed the genetic potential of being an Inhuman herself, so Shockley surprised her by breaking a Terrigen crystal in front of her. To his own surprise, it was Shockley and not Nadeer who underwent Terrigenesis and became a human bomb. He exploded in the office, killing Senator Nadeer. Shockley's body regenerated itself soon after.
