Daedalus

The Leader and Founder of The United Hero Front, a terrorist cell operating on the Eastern Seaboard dedicated to "bringing back what it means to be a hero". Not much is known about him, aside from what can be assumed from his "speeches": He wears an armoured red and black full-body exosuit. This man is considered powered, armed and extremely dangerous. If spotted, please alert your local Vanguard Office and wait for a response team to arrive.
 * He used to work with The Vanguard, position unknown
 * There is no data on him, though he isn't the one who expunged it
 * The Vanguard wronged him personally

Story
After consulting the aging Renegades, the party discovers the true identity of Daedalus: Darcy Edmonds. Presented with the choice of investigating Harvey and Hayden's old friend or turning this information in to Georges Frey, Harvey kept level-headed and decided to investigate what was really going on.

After a chat with the "terrorist" several facts became clear to us: Darcy arranged for his fake death by getting Isabel, Sean's wife, to make a clone of him before confronting Sean. He felt that he could only trust her with the truth because she could see it with her own eyes. Afterwards, he started planning on how to take out The Vanguard while still staying good in the eyes of the people.
 * 1) The Vanguard was irrevocably corrupt
 * 2) Sean was directly to blame for the deaths of Nancy, Cheri and Darcy's fake body
 * 3) Warlock is planning something

It was pretty handy Sean already erased all evidence of his existence for him.
