During the fourth season of Agents of S.H.I.E.L.D., Dr. Holden Radcliffe and Aida built a Life-Model Decoy of S.H.I.E.L.D. scientist Leo Fitz. This replica infiltrated the Playground along with LMD's of Phil Coulson, Jeffrey Mace and Alphonso Mackenzie as part of a plan to execute several known Inhumans for Anton Ivanov.
History[]
The Man Behind the Shield[]
When S.H.I.E.L.D. launched an operation to Russia to rescue Jeffrey Mace from the Watchdogs, the agents on the mission split up to search the SVR facility and find the Director. After the team had split up, Coulson, Fitz and Mack were ambushed and captured by Aida, who replaced the three of them with Life-Model Decoys. They, as well as the real Director Mace, were relocated to a submarine which fled shortly after. While Aida would plug the captives into the virtual environment of the Framework, the LMD's would return to the Playground and enact a plan to bring all known Inhumans on S.H.I.E.L.D.'s watchlist to one place where they could all be executed with ease.
Self Control[]
After the team returned to base, Jemma Simmons expressed concern to Fitz regarding how the mission had played out, noting there was an odd period of silence when none of the agents were in contact with each other. While Fitz initially dismissed this, Simmons looked over the security footage of the team's return to the Playground, discovering that the security system had detected four LMD's entering the base. According to the footage, the LMD's were Coulson, Mack, Mace, and Daisy Johnson. However, Fitz had entered the base ahead of them and Simmons had no idea that he was, in fact, the fourth LMD.
The Fitz LMD continued the deception as he noted that the LMD's were not aware that he and Simmons were onto them. However, they were soon joined by the Coulson and Mack LMD's who began asking questions to Fitz about the mission, allowing Fitz to maintain his cover. When the Mace LMD then ordered Simmons to bring all the Inhumans to the base, secretly planning on killing them, Fitz recommended that he and Simmons remain close together, telling Simmons he would keep her safe while wanting to scan her brain, as was his secret programming.
As they made their way through the base, Fitz discussed what had happened with Simmons, noting that Dr. Radcliffe would have used Melinda May's LMD to scan the agents to produce the LMD bodies. However, Fitz accidentally set off an LMD detector which Simmons soon noticed, at which point she drew her gun and threatened him. Fitz's LMD attempted to maintain his disguise by insisting he was not the machine, claiming Simmons was and did not even know it, noting how she had made him come to his quiet area with only her in order to then ambush her.
When Simmons continued to insist she was human, Fitz began accusing her of being the only one who was threatening him with a gun, crying tears in order to put doubt in Simmons' mind, with her begging the LMD not to make her feel sorry for it. Fitz told Simmons that he was the bad guy for ever helping Radcliffe build Aida and the LMD's before being ordered by Simmons to pick up a nearby blade and cut his wrist, so she could see if he was robotic or not, although Fitz argued that could mean she was a robot making him kill himself, but he agreed regardless of this.
As instructed, the Fitz LMD cut open his wrist, causing the artificial blood to come pouring out as he collapsed down onto his knees in apparent agony, claiming he may have cut open a vital artery as a result. The LMD ensured that he kept the bleeding wound in shadow and played the role of the victim in pain, causing Simmons to walk closer to him to try and patch up his wound. However, as soon as Simmons was close enough, the Fitz LMD stabbed her in the leg before knocking her gun away and striking her across the head with a heavy paint can.
The Fitz LMD then had Simmons lightly sedated so that he could then log her inside the Framework and prepared her own Quantum Brain for her own LMD. While setting up the process, Fitz reassured her by claiming that she would soon be able to rest and that he was doing this to keep her safe, which was that the real Leo Fitz had always wanted, so they could finally be married. When Simmons got off her chair and attempted to crawl away, grabbing a hammer to defend herself from him, the Fitz LMD calmly told her not to be afraid.
Simmons distracted the Fitz LMD by commenting on how he had mentioned marriage, before using the hammer to drop a large engine on him, trapping him underneath. Simmons then used this to her advantage by jumping on the Fitz LMD and stabbing him multiple times, causing him to scream out in apparent pain before performing as Fitz in order to make Simmons feel sympathy. Simmons, however, stabbed him in the neck, causing him to malfunction and shut down. The Coulson and Mack LMD's later found and repaired Fitz's circuitry and reactivated him to continue the mission.
Fitz discovered that Quake had also learned of their deception and had deactivated the Mack and Mace LMD's, with Fitz noting that it would take him a while to repair them both. Having just heard that Quake and Simmons had been captured by the May LMD, Coulson went to investigate while sending Fitz to activate the multiple Daisy Johnson LMD's being stored in the basement containment room. However, much of the base was destroyed by explosives before Fitz could do this when May's LMD triggered an explosion in order to enable Simmons and Daisy to flee. Fitz's LMD was also destroyed in the blast.
