Miles Lydon is a highly skilled computer hacker and member of the Rising Tide.
Lydon is a member of the "hacktivist" group known as the Rising Tide. Rising Tide is a group of like-minded hackers the world over who share a common belief-- that all information should be free and available to all who could use it.
Lydon was romantically involved with fellow Rising Tide hacker, Skye. Lydon taught Skye many computer skills that she used in her quest to find the truth about her parents.
Lydon remained in contact with Skye when she infiltrated S.H.I.E.L.D. hoping to find evidence about her parents' identity. When a hack of his brought him to S.H.I.E.L.D.'s attention, Skye warned him away with a text. Skye soon joined him in his Austin, Texas apartment.
Lydon was surprised to hear that Skye found S.H.I.E.L.D. to be less monstrous than they had imagined. However, after a brief romantic interlude, they were discovered and detained by Agent Melinda May.
Brought back to the Bus for interrogation, Skye tried to defend Lydon to her team as they flew to Hong Kong. However, the truth then came out-- Despite their shared ideals, Lydon accepted payment of one million dollars from a woman named Raina for information that was later used by her employers to endanger the life of a man named Chan Ho Yin.
Despite Lydon's insistence that he only did it so they could build a life together, Skye was horrified that Lydon would abandon his ideals like that. Realizing that he wasn't the man she thought him to be, Skye broke off their relationship.
Lydon later aided Agent Phil Coulson's team when their extraction mission went bad, and after it was over, Coulson offered Lydon a choice-- a cell or a Tracking Bracelet that would prevent him from using electronic equipment. Coulson then left him in Hong Kong without any money (as Coulson donated the money from the information about Chan to the family of slain S.H.I.E.L.D. Agent Quan Chen, who died on the mission) or any way to return home.
- Master Hacker: Miles Lydon is one of the world's greatest hackers, able to access information from computers around the globe. He is widely recognized for having hacked photos of Vladimir Putin. Among his other feats, he managed to hack S.H.I.E.L.D.'s information about one of the individuals that appear on their Index, Chan Ho Yin, and he was the one who taught Skye about hacking, before she became a master hacker on her own.
