Eli Morrow

Eli Morrow is the hidden main antagonist of the fourth season of ABC's Marvel's Agents of S.H.I.E.L.D. He is the uncle of Robbie and Gabriel Reyes.

He is portrayed by Jose Zuniga.

Past
Eli was an engineer who was assigned to work with Joseph and Lucy Bauer at Momentum Labs after becoming aware of an ancient book known as The Darkhold. After the Bauers built the matter-generating machine inspired by the Darkhold, Eli was seemingly concerned that Joseph had become obsessed with the machine and tried to warn Lucy, but when Lucy dismissed Eli's concerns, Eli realized that Lucy was just as insane as her husband was. When the machine exploded, turning everyone except Eli and Joseph into ghosts, Eli held Joseph responsible for what happened and put him in a coma.

Marvel's Agents of S.H.I.E.L.D.
Eli is currently in prison on charges of attempted manslaughter. He first appears when Agent Phil Coulson visits him in prison to alert him of Lucy's return and reign of terror, but he doesn't believe Coulson at first, but when Robbie visited him on S.H.I.E.L.D.'s behalf, he told him everything that happened with Joseph and warned Robbie to steer clear of the Darkhold. Later on, Lucy arrived at the prison and kidnapped Eli and took him to the long-abandoned Momentum Labs. She then forced him to read the Darkhold while she finished building the machine. Once the machine was built, Eli entered it and gained the ability to create matter from nothing.
