A.D. Doug is a writer and scientist who diverted from the Sacred Timeline, causing him to be abducted by He Who Remains and have his memory wiped to be a Time Variance Authority agent. Now named Ouroboros and working in Repairs and Advancement, he had no memory of his past life or that he was a Variant. Ouroboros worked for years in the TVA, even gaining the nickname of O.B. He also helped Loki stop Time Slipping while simultaneously trying to fix the Temporal Loom to fit all of the branches that were coming from the Multiverse.
