"S.H.I.E.L.D. is just as guilty of the same thing – experimentation without thought of consequence! Your search for an unlimited power source brought an alien invasion."
―Franklin Hall to Phil Coulson[src]

Franklin Hall was a S.H.I.E.L.D. asset and a Canadian scientist who became famous for his work and theories on the extremely rare element known as Gravitonium. Desiring to escape S.H.I.E.L.D., he leaked his location to his former friend Ian Quinn who freed him hoping that Hall could find a way to weaponize Gravitonium. Hall disagreed with Quinn and sought a way to destroy the Gravitonium, but before he could, he was caught up in a fight with Coulson's Team who had been called in by S.H.I.E.L.D. to rescue him. During the fight, he was dropped into the Gravitonium by Agent Phil Coulson.


Early Life

"Do you remember, in all our talks on Orchard Street, the part where it's very, very dangerous?"
"Everything powerful is dangerous."
―Franklin Hall and Ian Quinn[src]

Franklin Hall is a brilliant scientist from Canada who went to University of Cambridge with Ian Quinn. The two became friends as they shared the belief that all information should be free to whomever can use it. Hall also developed his theories about the rare and mysterious element known as Gravitonium during this time. Hall recognized the danger of his theoretical element, whereas Quinn thought only of how to exploit it.

Later in life, Hall became an instructor for S.H.I.E.L.D. where, as a chemical kinetics advisor, he taught such promising young cadets as Leo Fitz and Jemma Simmons.[1]

Plans with the Gravitonium

Working with Ian Quinn

Hall is found while transported by S.H.I.E.L.D.

"We can't let Quinn have control of this. It’s too dangerous."
"We can't let anyone have control of this. That's why I'm here, to bury it at the bottom of the ocean, with him."
Phil Coulson and Franklin Hall[src]

After discovering that Ian Quinn had discovered a large quantity of Gravitonium and fearing what Quinn would do with such power, Hall arranged to have himself kidnapped by Quinn and brought to Malta, where Hall pretended to work with Quinn towards his goals. In truth, Hall was determined to destroy the Gravitonium, along with Quinn and himself, in order to keep the world safe.[1]

Infiltration into Ian Quinn's Mansion

"My team's here. Good people."
"Sworn to protect all mankind? That's what I'm doing, I promise. Making things right."
Phil Coulson and Franklin Hall[src]

What Hall didn't anticipate was a S.H.I.E.L.D. extraction operation led by Agent Phil Coulson attempting to effect Hall's rescue. Coulson, after determining that Hall's plan would harm much of the local population, disrupted Hall's plan and shut down the gravitational generator. After a scuffle, the gravitational after-effect from the generator drew Hall into the mass of Gravitonium, enveloping him inside.[1]


"It consumed them. Franklin wanted revenge, but now he's stuck with him, forever."
"They're inside the Gravitonium."
"Their minds. Their rage."
Carl Creel and Hale[src]
This section needs a rewrite

Coulson ordered the mass of Gravitonium be secured in an unmarked vault at The Fridge, a S.H.I.E.L.D. storage facility. Unknown to Coulson, Hall still lives within the mass of Gravitonium and seeks to escape.[1]

Hall is permanently enveloped in Gravitonium.

When Victoria Hand planned to capture the Bus because she believed that Coulson's Team were undercover HYDRA agents, Grant Ward discussed with Coulson the different assets on board, believing that the Gravitonium was one of them. Coulson corrected him, revealing its location.

Later, Hand listed to Simmons the various "crimes" of Agent Coulson to prove to her that he was a traitor; in that list was the death of Franklin Hall.[2]

During the HYDRA Uprising, the Gravitonium - with Hall still trapped inside - was discovered and taken from the Fridge by HYDRA Agents John Garrett and Ward during an infiltration mission. The mass of Gravitonium was then delivered to Ian Quinn, unbeknownst that Hall is living within it.[3]

Sometime later when John Garrett was empowered by the super-serum Raina constructed for him (which enabled him to see the Universe for what it was "underneath"), he was observing the Gravitonium mass and remarked to Raina about its latent potential.[4] After Quinn and Raina escaped Garrett's facility with the element, Raina informed Quinn that Hall's consciousness within the element "wanted" Quinn. Raina then opened up the container, allowing the Gravitonium to suck Quinn into it, trapping his consciousness within it along with Hall's.[5]

For years, Hall and Quinn were trapped in the Gravitonium, arguing constantly. When Carl Creel attempted to absorb the Gravitonium to replicate it's properties, he was haunted by the voices of both Hall and Quinn.[6] Glenn Talbot later absorbed the Gravitonium himself and was able to silence out Hall and Quinn. At the climax of the Battle of Chicago, Hall, Quinn and Creel were all killed when Talbot and the Gravitonium were ejected into space by Quake.[7]


"I am doing the right thing, a completely selfless act. I know that history never celebrates what didn't happen. They'll call this a... a tragedy. They won't understand the good I did here."
"Killing innocent people?"
"Saving millions. We have to live with the choices we make, but sometimes, we have to die with them, too."
―Franklin Hall and Phil Coulson[src]

To be added


"Guess which genius published every theory about gravitonium and possible applications, years ago."
Leo Fitz[src]



  • Smith & Wesson M&P: Hall stole Phil Coulson's sidearm and used it to hold the agent at gunpoint while attempting to destroy the Gravitonium. However, Coulson soon reacquired and used the pistol to shatter the glass floor, plunging Hall to his death.[1]






In chronological order:


  • In the comics, Dr. Franklin Hall becomes the super-powered villain Graviton in the Rocky Mountains. His S.H.I.E.L.D. transport being labeled with "Rocky Mountain Office Supply" is a reference to this fact.

Behind the Scenes

  • Franklin Hall was originally intended to be a recurring character before his role was reduced to a single episode, which angered Ian Hart.[8]
