Tony Diaz

Tony Diaz was a fireman stationed in Wrigley, Pennsylvania.

Biography
After the Battle of New York, Diaz was called with his co-workers (Adam, Baker and Justin), and other fire crews to douse fires in the area and making sure everyone was safe. During their time there, Diaz found a Chitauri helmet and took it with him as a souvenir.

Diaz kept it in a display case at the fire station in Wrigley, but contracted an alien disease by taking it out of the case and polishing it months later. Coulson's S.H.I.E.L.D. team tracked him down and assumed him to be the killer of Cross, but when Coulson learned the truth he sat down with Diaz to reassure him about death and finality before exiting the fire station and leaving Diaz to his inevitable fate.
