Angar was a cancer patient and a test subject for an experiment wherein his vocal cords were hit with an experimental energy blast. The energy blast destroyed the cancer cells, but altered his voice so that it affects the central nervous system of others; anyone who hears so much as a whisper from him will immediately go into a catatonic state.
Fight On Edit
In "One of Us", Cal broke into Brynmore and freed Angar. Cal then promised Angar an opportunity to get revenge on S.H.I.E.L.D. and a chance to show the whole world what S.H.I.E.L.D. does to gifted individuals like them.
Cal next led his team to Mantiowoc, Wisconsin, Coulson's home town, ensuring Angar and the others that S.H.I.E.L.D. would come to them. Angar and the others then attack a local high school where Angar lets out a loud scream which causes all the students present to fall unconscious. The effect also takes out all birds flying over the field at the time.
Coulson and his team do appear, however, right in the middle of a stand-off, Gordon teleports in and grabs Cal before teleporting out. Coulson then punches Angar in the neck so he can't speak and knocks him out.
- The sound of his voice can cause anyone who hears to go into a catatonic state.
