"Take the elevator to the basement, find the rift, turn that puppy on, put it in the rift, then get the hell out of there."
"I wish it were that simple."
Phil Coulson and Leo Fitz[src]

The Closure of the Fear Dimension's Rift was the result of Phil Coulson using a Gravity Containment Device created by Leo Fitz to contain the so-called "Fear Dimension" which had opened in the Lighthouse.


"I don't understand how, but it seems that this dimension can take our deepest fears and it can manifest them physically."
Leo Fitz[src]
Fear Dimension

The Fear Dimension opened in the Lighthouse

Having been lured into the St. Louis Aerospace Facility by General Hale, S.H.I.E.L.D. brought back the Kree Orb which had been used to trick them into the Lighthouse, stored along with the Monoliths. However, it turned out that the Kree Orb had been rigged with a bomb. Although the Chronicom Noah attempted to contain the explosion, the blast destroyed the three Monoliths, creating a spacetime rift onto what Leo Fitz called a Fear Dimension.[2]

The Fear Dimension generated several recreations out of the S.H.I.E.L.D.'s agents' minds. These recreations attempted to murder them on several occasions, prompting Fitz to create a Gravity Containment Device in order to end the phenomenon and avoid that it spreaded outside the Lighthouse. However, the device needed to be put right into the rift, putting the one accomplishing the mission in real danger. Phil Coulson offered to be the one, which triggered an argument and ultimately forced Coulson to reveal that he was dying.

Nonetheless, Coulson managed to convince his colleagues that he had to do the job himself. In the meantime, he also tasked Deke Shaw with gathering several former S.H.I.E.L.D. agents.[1]


The Real Deal 31

The recreation of Mike Peterson greets Phil Coulson

"What are you doing, Coulson? Pick up the doodad. Let's go!"
Deathlok to Phil Coulson[src]

Equipped with a gas mask, a gun and the Gravity Containment Device designed by Leo Fitz, Phil Coulson went down into the subterranean levels of the Lighthouse. He soon encountered an recreation of Mike Peterson, who told him that the air was breathable. Although Coulson held him at gunpoint, Peterson promised that he would not try to harm him nor would he keep Coulson from fulfilling his mission.

However, Peterson also hinted that not only he was not real, but that everything Coulson believed to have lived since the creation of his team was fake as well and that Coulson was still on the operation table being resurrected. At first, Coulson elected to ignore what Peterson claimed, but Peterson insisted that everything he said was true, explaining that Coulson had lived in his mind what he wished to have lived in real life.

The Real Deal 30

Mike Peterson attempts to force Phil Coulson into the Fear Dimension

Coulson refused to believe what Peterson said, but his counter-arguments progressively lost in conviction, to the point that Peterson was able to take Coulson by the arm and slowly lead him to the Fear Dimension rift. However, at the last moment, Coulson retook control and told Peterson he did not believe him. Angered, Peterson tried to forcefully take Coulson to the Fear Dimension, only to be destroyed by the real Deathlok, who had been brought to the Lighthouse by Deke Shaw.

Deathlok vs Lash TRD

Deathlok destroys the recreation of Lash

As Deathlok helped Coulson to get back onto his feet, they were attacked by another recreation in the form of Lash. Deathlok jumped over it and destroyed it by firing a rocket at it. Then, two recreations of Vrellnexians joined the battle. Deathlok destroyed one while Coulson picked up the Gravity Containment Device he had dropped earlier and shot at the other creature, causing them to vanish.

Gravity Containment Device Activated

Phil Coulson activates the Gravity Containment Device

Coulson ultimately activated the Gravity Containment Device, which automatically levitated towards the rift. Upon fitting into the rift, the Gravitonium embedded in the device released its potential, causing Coulson and Deathlok to be drawn towards the rift. In the same time, they were attacked by a last recreation: Hive.

Spacetime Rift Contained

The Fear Dimension is closed by the Gravity Containment Device

Coulson and Deathlok managed to resist the attraction of the Fear Dimension and to destroy the recreation of Hive, which vanished like the others. Eventually, the device successfully shut down the Fear Dimension, much to Coulson's and Deathlok's relief.[1]


"The Gravitonium device that we used to seal the rift is barely strong enough. So, we need more Gravitonium to seal the rift for good."
Leo Fitz[src]
The first Gravity Containment Device drastically limited the influence of the Fear Dimension within the Lighthouse. Before the recreation of a forest created out of Deke Shaw's mind vanished like the previous ones, Leo Fitz and Jemma Simmons took advantage of this idyllic environment to finally get married.[1]

However, the device did not permanently and completely shut down the Fear Dimension, which kept generating recreations from time to time. Therefore, S.H.I.E.L.D. searched for more Gravitonium to create a more reliable device to contain the Fear Dimension. Although they successfully got some in the Principia[3], Fitz had trouble compressing the element enough to create a new Containment Device.

Permanent Closure Fear Dimension

The new Gravity Containment Device closes more permanently the Fear Dimension

It ultimately took a serious psychic split from Fitz, causing the release of his dark personality of The Doctor and the forced and painful removal of Daisy Johnson's Inhuman Control Device to eventually have a way to compress the Gravitonium and create a new Gravity Containment Device. This new device was taken by Johnson to the partly contained Fear Dimension: both the Containment Devices were combined and permanently shut down the Fear Dimension.[4]

Phil Coulson's duplicate possessed by Sarge

Unknown to everyone, when Phil Coulson closed the rift to an alleged Fear Dimension, the Black, White, and Grey Monoliths created a copy of him that was sent through time and space hundreds of years ago and to a world inhabited by non-corporeal beings, where an individual known as Pachakutiq took over his body. When this happened, Coulson's memories intermingled with Pachakutiq's in a fashion that caused both sets of memories to be clouded, causing Pachakutiq to believe that he had had a family that his lover Izel had murdered. This led him to start a crusade to kill her and wipe out the Shrike, adopting the name Sarge.[5] His evil doppelgänger was eventually killed by Alphonso Mackenzie with Izel before they could doom Earth.[6]
