In Thor, astrophysicist Erik Selvig works with Jane Foster, the daughter of a former colleague of his, on her wormhole research. They become involved in an encounter between Thor and S.H.I.E.L.D., leading to his employment by the latter to study the Tesseract—he accepts the job due to influence by Loki. In The Avengers, Loki uses the Tesseract to travel to Earth, and places Selvig under the control of the Mind Stone. Selvig is eventually freed of this control and able to help stop Loki's invasion of Earth, but is left traumatized by his experience. Selvig is able to help Thor again in Thor: The Dark World, and by Avengers: Age of Ultron appears to have recovered, working at Royal Holloway. After the defeat of Ultron, Selvig begins working for the Avengers. When Thanos snapped his fingers, and half the universe's population were disintegrated, Selvig was among those who were killed, and were subsequently resurrected by Bruce Banner five years later. In Spider-Man Far From Home, Selvig is shown to be starring in the documentary NOVA: Einstein Rosen Bridges with Dr. Erik Selvig.
