Mike Peterson, also known as Deathlok, is a recurring character in Marvel's Agents of S.H.I.E.L.D., first appearing as a minor protagonist in the first half of Season 1, and an anti-villain in the second half. He later appeared as a supporting protagonist in the second half of Season 2 and the 100th episode of Season 5.
Michael ''Mike'' Peterson is a former S.H.I.E.L.D. agent who was just a normal man until he was recruited into the Centipede Project. They granted him superpowers through the use of the Centipede Serum. However, when Peterson compromised all the secrecy of the project, they decided to terminate him but were stopped by Agent Phil Coulson and his S.H.I.E.L.D. agents. Some time later, Peterson had decided to rejoin S.H.I.E.L.D. as he joined Coulson's team. However, Peterson was later recaptured by the Centipede Project and transformed into their cybernetic assassin Deathlok. He was used by the Clairvoyant to keep people off his trail.
After the destruction of the Centipede Project and death of John Garrett, Peterson decided to go off on his own to find redemption for his past actions as Deathlok. During this time, he was recruited into the new S.H.I.E.L.D. under Phil Coulson's leadership. Coulson gave him the mission to hunt down HYDRA leader and scientist Doctor List, who was working on enhanced powered individuals and experimenting on them. He was eventually captured and tortured by List but was shortly after rescued by S.H.I.E.L.D. After being rebuilt, he continued his solo mission to protect innocent lives, eventually coming to Coulson's aid to close a portal to the Fear Dimension before he then returned to his solo mission rather than rejoining S.H.I.E.L.D.
Mike is a very driven individual, his sense of duty primarily stemming from his desire to do right by his son, Ace. However, this desire has caused him to strike deals with dangerous people without realizing the full implications of his actions. Despite this, Mike is a truly honorable man who did what he did for the right reasons and not for selfish greed. He is also very kind, having a good relationship with his son whom he loves very much, and remaining on good terms with Skye and the rest of S.H.I.E.L.D. despite their earlier transgressions and serves both as a way to support his son, and in gratitude for them stabilizing his enhancement.
