"We need to scan and replace those last two immediately."
"Carefully, undetected. We're still outnumbered here."
"Not for long. In the meantime Daisy will contact the Inhumans, inform them she's coming to collect them personally?"
"Yes, and then execute them on sight."
―Mace LMD and Coulson LMD[src]

Jeffrey Mace was the Life-Model Decoy of the real Jeffrey Mace who was sent on a secret mission by Holden Radcliffe to infiltrate S.H.I.E.L.D. and execute all the Inhumans for Anton Ivanov. The LMD's plan was revealed however and Mace attempted to rally the remaining S.H.I.E.L.D. agents against those who had discovered their plans, only to be confronted by Quake who fought against Mace LMD to keep herself from being put in the Framework until she gained the upper hand and destroyed the robot.


LMD Mission

Manipulating S.H.I.E.L.D.

"I've recovered enough."
"My god, that was fast."
"A little sore, but I'll manage. I think Daisy here should contact the Inhumans personally - and oversee their transfer to H.Q."
―Mace LMD and Jemma Simmons[src]

Mace is aided by the other Life-Model Decoys

Having been captured by Anton Ivanov, the real Jeffrey Mace was tortured by Ivanov and then beaten by Russian thugs. As Phil Coulson and Alphonso Mackenzie were helping him out of the Russian bunker, they was captured by Holden Radcliffe and Aida and replaced with Life-Model Decoys that were sent to infiltrate the Playground. Mace's LMD pretended to be injured as he was dragged out and regrouped with Jemma Simmons and Daisy Johnson, at which point Phil Coulson's LMD ordered everyone to return back to the Playground to continue their mission.[1]

Mace's LMD gives orders to the other agents

Once back at the Playground, Mace's LMD then arrived in the lab, claiming to have recovered well enough from his ordeal against the Superior and spoke with Simmons and Leo Fitz's LMD, informing them that they were planning on bringing all of the remaining Inhumans to the base for their own protection, claiming that Ivanov was clearly ready to complete his plans for the Watchdogs. Mace's LMD then tried to get Simmons alone in his office to scan her brain too, however Simmons and Fitz's LMD made a point that they wanted to stick together throughout their mission

Mace speaks with Phil Coulson's LMD

Mace's LMD then spoke with Coulson's LMD about their need to scan and replace Simmons and Johnson as soon as possible without being detected, as Coulson noted that they were still outnumbered inside the base. Coulson then explained that in the mean time Johnson would be contacting all the Inhumans and bringing them to the base ready to be executed on site, as were Ivanov's orders. Coulson's LMD then reminded Mace's LMD to collect the Daisy Johnson LMDs from Zephyr One and bring them onto the base ready to soon replace her as soon as was possible.[2]

Schemes Discovered

Mace prepares to kill his S.H.I.E.L.D. agents

"Shoot to maim stomach, spine. It's imperative we pull the data from their heads."
"Don't let their faces cloud your judgment."
―Mace LMD and Coulson LMD[src]

When Leo Fitz's LMD was destroyed by Jemma Simmons who had discovered their deception, Mace and Phil Coulson's LMDs were called to look at his body. Mace attempted to tell Fisher and the other agents that Simmons was the Life-Model Decoy, however it was soon discovered that Fitz was in fact a robot. Before the entire base could be scanned, Coulson shot the two agents before Mace struck the other one with incredible force while Coulson beat him to death.

Mace LMD gives his agents their orders

They were then informed by Alphonso Mackenzie LMD that Daisy Johnson had also learned the truth. Mace then put the entire base onto lockdown, shut down the security feeds before putting on the Patriot Suit and gathering the remaining S.H.I.E.L.D. agents together. Mace's LMD then proceeded to tell all of the agents that Johnson and Simmons had been kidnapped and were in fact the Life-Model Decoys, ordering them not to be fooled by their appearance and shot them in either their chest or their spine in order to preserve their own brains before Mackenzie's LMD ordered them to move out.

Mace witnesses Quake's bomb attack

Just as Mace was exploring the Playground with Coulson's LMD, he gave orders to his men before witnessing a small car driving via remote control throughout the base before crashing against a wall. Mace's LMD went to investigate before a bomb was detonated, causing sleeping gas to run through the entire base and knock out everyone but the LMDs. Coulson noted that this was a smart move before Mace ordered the lights to be shut off as they could use their Backscatter X-Ray Eye Implants to see better in the dark than normal humans could, which Coulson agreed with.[2]

Showdown with Quake

Mace's LMD is attacked by Quake

"Really? Not even winded?"
"We don't want to hurt you."
"That's not what it feels like."
Quake and Mace LMD[src]

As Mace's LMD explored the wreckage of the base, he was suddenly shot multiple times by Quake using the Shotgun-Axe, all of which he was unharmed by. Quake then attempted to strike him with the axe blade, only for the Mace LMD to catch it midair, disarming Quake and knocking her down. The pair then engaged in a fight in which Quake soon proved herself to be the superior fighter, using her own Inhuman powers to give herself even more of an edge against Mace's LMD.

Mace insists he does not want to hurt Quake

However Mace proved himself to be much stronger and could not feel pain despite all of Quake's many attacks, with her launching herself into the air and using her shockwave powers to land heavier blows which did knock Mace back. Their fight soon moved into the burning lab, with Quake noting her frustration that Mace was not even winded at all from the fight while she was nearly completely exhausted. The Mace LMD insisted that it was not his intention to hurt her and only upload her mind into the Framework to live in peace, but Quake noted that was not how it felt.

Mace's LMD is finally destroyed by Quake

Quake then continued fighting as she struck Mace over the head with a computer screen. Quake continued striking the Mace LMD with any weapons near her until she fired a shockwave right under his feet, knocking him over, before stabbing him with an electric weapon, which short-circuited all of his robotics and killed the machine. Mace Coulson and Mackenzie used the opportunity as Quake tried to recover to capture her, they both failed and Mace's LMD body was later destroyed when Melinda May's LMD blew up the entire base in a massive fireball which destroyed the other LMDs.[2]
