phased or invisible objects through his immediate awareness of gravitational fluctuation and while he was not able to invoke dimensional portals, he was at least able to close them. He could simulate vast superhuman strength and durability using gravitonic fields to surround his body, but he could not actually manipulate density or increase his physical strength. Aside from his powers to manipulate gravity, Hall had a PhD in Physics and was intellectually brilliant, with expertise in advanced physics, including teleportation. His greatest limitation was that he was emotionally and mentally very disturbed. In other media Television Graviton appears in The Avengers: Earth's Mightiest Heroes two-part episode "The Breakout", voiced by Fred Tatasciore. This version is a physicist hired by S.H.I.E.L.D. to help them recreate the super-soldier serum that created Captain America. However, Hall caused an accident that gave himself near-limitless gravitational powers. Soon after, when it became clear that he was now dangerous, S.H.I.E.L.D. Director Nick Fury placed Hall into an unconscious state and imprisoned him at the Raft. A decade later, when a technological problem occurred at the Raft, Graviton is freed and seeks revenge on Fury, only to be foiled by Thor, the Wasp, Iron Man, the Hulk, and Ant-Man. Two variations of Graviton appear in the Marvel Cinematic Universe series Agents of S.H.I.E.L.D.. Dr. Franklin Hall appears in the season one episode, "The Asset", portrayed by Ian Hart. This version is a Canadian physicist who was abducted by his former partner, Ian Quinn, to finish work on a gravity manipulator powered by a liquid metal-esque gravity-manipulating substance called gravitonium. Believing the gravitonium is dangerous, Hall attempts to destroy the device. S.H.I.E.L.D. agent Phil Coulson tries to save Hall, but the latter is pulled into the gravitonium. The substance reappears in the episode "Providence", when Hydra agents release it before their leader John Garrett gives the gravitonium back to Quinn. In a flashback depicted in the season five episode "Inside Voices", Quinn was also absorbed by the gravitonium following Garrett's defeat and has been arguing with Hall inside the substance ever since before Hydra eventually reclaimed it. During season five, Ruby Hale, a genetically-engineered Hydra agent, invades a subterranean Hydra facility and infuses herself with 8% of the gravitonium. She fails to control her newly acquired gravity-manipulating powers and kills one of Hydra's leaders, Werner von Strucker, before she is killed by S.H.I.E.L.D. agent Elena Rodriguez and S.H.I.E.L.D.
