R. Giyera was a villainous supporting character in Season 3 of Agents of S.H.I.E.L.D.. He was an Inhuman who possessed line-of-sight based telekinesis that allowed him to manipulate any non-organic object with his mind. He put these powers to use as an assassin working for HYDRA, first under the leadership of Gideon Malick and later under the sway of Hive.
Death[]
In the Season 3 finale "Ascension", Hive and Giyera had hijacked Zephyr One in order to deliver a warhead loaded with a Terrigen-based virus into the atmosphere, which would transform most of humanity into Primitive Inhumans once dispersed. However, Melinda May and Leo Fitz had managed to sneak aboard the craft. While May was able to take out the Primitives guarding the warhead, she was then knocked out by Giyera. Before Giyera could kill May, Fitz emerged from the vent in the floor and threatened to use a hidden weapon to destroy the plane and kill everyone aboard.
Giyera listened to Fitz monologuing and how there was a weapon on board the ship that would destroy him if he fired his sub-machine gun, promising that they did not blame the Inhumans who were under Hive's control. However, Fitz explained that he viewed Giyera as a murderer before he had been swayed and then unveiled a cloaked gun in his hand, firing several shots into Giyera's chest and killing him.
