Angar the Screamer
Angar the Screamer (David Angar) was born in San Francisco, California. He became a hippie and a radical social activist, who volunteered for an experiment that would give him superhuman powers. Moondragon provided a crooked lawyer named Kerwin J. Broderick with a machine built on Titan. The machine subjected Angar's vocal cords to a bombardment with hypersound. As a result, Angar could scream very loudly and cause people to hallucinate. Moondragon intended for Angar to be an ally against the mad Titan Thanos, but Broderick hired Angar as an assassin. In his first appearance, Angar tried to kill Daredevil and Black Widow. Angar was defeated and would fight many Marvel superheroes over the years. He tended to attack civilians for little or no reason.
