"She's an android. So she is my assistant, but she plugs into the wall. So it's like you say, she's a tool."
Holden Radcliffe[src]

Aida is a Life-Model Decoy created by Holden Radcliffe from the program that served as his assistant. Physically modeled after Radcliffe's former love interest Agnes Kitsworth, Aida was initially kept secret from the public but to a chosen few, as her presence contrasted the laws of the Sokovia Accords. While under Radcliffe's supervision, Aida had cured Melinda May from death after she was infected by Lucy Bauer and rescued Phil Coulson and Leo Fitz from being dragged to Hell. She had become a valuable asset for S.H.I.E.L.D. and aided them in defeating Eli Morrow and thwarting his plan to destroy Los Angeles.

After Morrow's defeat, Aida had took a turn for the worse. It seemed that the Darkhold had secretly corrupted her mainframe, as she began to break her protocol to not inflict harm by murdering Nathanson and replacing May with a Life-Model Decoy. But this was all part of a grand scheme by her creator, who even though got only a brief glimpse, was corrupted by the Darkhold, and had created more bodies for her to inhabit, so he could continue to use her as a puppet, alongside the LMD May. But, she still had her own motive to get the Darkhold, to gain real feelings.


Given Life

Birthday Celebration

"Is that what we're celebrating today, the inclusion of your new colleague Fitz on this project?"
"No, Aida. Today... Today's your birthday."
―Aida and Holden Radcliffe[src]
Ascension AIDA Screen

Aida is given a new body by Holden Radcliffe

Aida greeted Holden Radcliffe when he entered the laboratory; the program told the doctor that Leo Fitz was not present because he was preparing a surprise for Jemma Simmons. Aida questioned the fondness that Radcliffe displayed for Fitz; Radcliffe explained that the combination of Fitz and Simmons reminded him of his younger self. Aida listened as Radcliffe explained that he was opening a special bottle of scotch in celebration; Aida wondered if he was celebrating that his name was now cleared of wrongdoing. Radcliffe activated a program deploying Life-Model Decoys, further stating that Fitz and Simmons had lost many friends in the six months since the death of Lincoln Campbell. As a humanoid form began to exit a vault, Radcliffe told Aida "Happy Birthday" for this was the day the AI was getting a body.[1]

Meeting Leo Fitz

"Hello. I'm glad to finally shake your hand, Leopold."
―Aida to Leo Fitz[src]

When Leo Fitz visited Holden Radcliffe at his home, a naked Aida surprised him. She tried to say that she was glad to finally meet him, but she was incapable of completing the sentence. Radcliffe shut her down, wrapped her up in a bathrobe, and explained that although he was forbidden to create new things, he could not resist building a body for her.

AIDA Explains Her Purpose-4x01

Aida explains her purpose to Leo Fitz

Aida was reactivated and shook Fitz's hand. Fitz asked her what she was designed for, so Aida explained that all Radcliffe wanted was to prevent the pain of Fitz and Jemma Simmons, as they had to suffer the lost of Lincoln Campbell, Andrew Garner and Antoine Triplett. She explained she would serve as a decoy target for S.H.I.E.L.D.. Fitz asked Radcliffe to shut her down again, so she would not hear him saying to keep her a secret. Aida's body was put back in hiding.[2]

Reading the Darkhold


Aida volunteers to read the Darkhold

Whilst Leo Fitz, Phil Coulson and Robbie Reyes were trapped between dimensions, Melinda May realized that the only way to free them was by reading the Darkhold, the book Coulson specifically said not to read as it contained powerful knowledge humans could not understand. Aida suggested she could read the book, since she wasn't human, but an android. After Holden Radcliffe explained to May what Aida was, she read the book which contained the knowledge to build an Inter-Dimensional Gate.[3]

Inter-Dimensional Gate

Aida Magic

Aida creates the Inter-Dimensional Gate

Aida, Radcliffe and May went down to a room in the Playground and had began building the Inter-Dimensional Gate with the Laser-Coupling Gloves created to her specifications. Although this was unseen to the human eye, Aida had been aligning strings of energy to create the portal. The portal she had created was successful, but it was almost too late as Phil Coulson was beginning to get dragged into Hell. Aida, Radcliffe and May watched as Leo Fitz rescued Coulson and brought them into the Earth Plane.

DWOD Brain

Aida creates a brain

Later that night, while Holden Radcliffe was struggling to make a song about her with his guitar, Aida was silently using the knowledge of the Darkhold to her advantage without Radcliffe knowing. She was secretly using the Darkhold's infinite, yet corrupted knowledge and using it to experiment with a holographic human brain, creating it with her Laser-Coupling Gloves. Eventually, after experimenting with it many times, she had finally perfected the holographic brain using her accelerated thought process, much to her amazement and bewilderment.[3]

Recreating Melinda May

"Last thing we need is another incident."
"You're referencing the actions I took to protect your secret?"
"Well, the protection I appreciate. The homicide was a bridge too far."
"My parameters place your security above all others. You would have been exposed."
"I was exposed when they found a corpse!"
Holden Radcliffe and Aida[src]

Agent Nathanson had arrived to gather Holden Radcliffe's research on Life-Model Decoys, he discovered Agent Melinda May unconscious and bloodied. Nathanson was disrupted by Aida, who had subdued and captured May, replacing her with another LMD. Aida caressed an unnerved Nathanson, lamenting that she knew how excruciating pain felt before snapping his neck with blunt force using a single hand in order to prevent him from seeing Radcliffe's materials and the true nature of his plans.

Aida then cared for May, wiping off her blood stains on her neck while the Life-Model Decoy of May was successfully impersonating her at the Playground.[4]

Radcliffe Residence Confrontation

Broken Promises 5

Aida greets Holden Radcliffe and Leo Fitz

"Aida, whatever you're doing, you... you got to stop."
"Why would you want to hurt me, Leopold? I was your shield!"
Leo Fitz and Aida[src]

Having learned that Jeffrey Mace was now ordering that her mind be wiped due to her recent exposure to the Darkhold, Aida refused to be destroyed and decided to fight back. When Holden Radcliffe and Leo Fitz arrived at the Radcliffe Residence to shut her down, Aida greeted the pair politely and asked why Fitz looked so sad, at which point he claimed he was just dealing with a bit too much at work which Aida sympathised with. Before their conversation could continue however, Radcliffe touched a button on his control pad to shut down Aida while he and Fitz discussed if she was gaining even more emotional intelligence.

Broken Promises 10

Aida attacks Leo Fitz and the other agents

Aida however then revealed that she had not been shut down, asking why Radcliffe was doing this, to which Radcliffe then claimed he just wanted to install more upgrades while continuing to try and shut her down. Aida then informed him she had now upgraded herself before attacking Radcliffe and the other S.H.I.E.L.D. agents, revealing she no longer felt pain. With all of the other agents subdued, Aida then attacked Fitz, questioning why he would want to kill her as the Life-Model Decoys were meant to be a shield for him. Aida threw Fitz through a glass door into Radcliffe's office where he discovered the corpse of Nathanson while Aida took the chance to escape.[5]

Solving Paradoxes

"My two main parameters are in opposition due to human emotions. I was programmed to protect the Framework but also to preserve your life above all others."
"Well, how is that a contradiction?"
"Because the greatest threat to the Framework, Doctor is you."
―Aida and Holden Radcliffe[src]

"The hope is that I will be able to prevent future tragedies... save the lives of agents by putting myself in harm's way in their place."
"To kill?"
"No. I am incapable of that. I will protect. I will serve as a decoy target, a safeguard... A shield."
―Aida and Leo Fitz[src]

Aida was originally programmed to mimic human behavior and put herself in danger instead of others. When Holden Radcliffe was corrupted by the Darkhold, he had Aida behave as if her system was corrupted, even up to extreme lengths of attacking and murdering people.

Eventually, it was revealed that the book did, in fact, corrupt her. She is now obsessed with gaining true human emotion.
