Tony Almeida

Anthony "Tony" Almeida was a federal agent who worked for CTU Los Angeles from its inception. During that time, he was promoted to Special Agent in Charge. After aiding the bio-terrorist Stephen Saunders during Day 3 to keep him from killing his wife, Michelle Dessler, Tony was arrested and sent to prison on charges of treason. After his release, Almeida worked for CTU on a provisional basis before moving away with Michelle. On Day 5 he was grievously injured in the CTU medical clinic by Christopher Henderson and believed to be dead.

Tony survived, however, and joined David Emerson's mercenary group for three years. He was also a key operative in the conspiracy by Alan Wilson and the Prion variant cabal in their plan to use terror to gain a more active role in the United States' military affairs. However, he was actually helping this organization for the sole purpose of meeting Wilson face-to-face and killing him in revenge for the death of Michelle and their unborn son.
