Eugene "Flash" Thompson is a former student of Midtown School of Science and Technology. While at the school, Thompson would frequently torment his classmate and decathlon partner, Peter Parker, by constantly deriding Parker's claims to have worked with Tony Stark and to personally know Spider-Man, which he refused to believe was possible. However, Thompson's own admiration for Spider-Man continued to grow, following him being saved from the Washington Monument, as well as encountering Spider-Man again when the hero had confronted Vulture during homecoming and taken Thompson's father's car.
Thompson was killed by Thanos, but was resurrected five years later. He then returned to school life as he continued to mock Parker and began a live-streaming social media platform when they departed on a school trip to Europe. While Thompson admired Spider-Man for his heroics back in New York City, he had witnessed the worldwide heroics of Mysterio, who saved him in Venice from an attack by Hydro-Man. While his class toured around Europe, Thompson continued live-streaming while witnessing more attacks from the Elementals, including the final battle against the Elemental Fusion, which had fought Mysterio until being mysteriously erased from existence. Thompson and his friends were then rescued from attacking drones by Happy Hogan and Spider-Man, allowing Thompson to return to New York City.
When Parker's identity of being Spider-Man was exposed, Thompson wrote a book to capitalize on the sensation by posing as Parker's "best friend". After being admitted to Massachusetts Institute of Technology, he informed Parker where the Vice Chancellor was so that Parker could get Michelle Jones and Ned Leeds accepted. Shortly after, Thompson's memories of Parker, including him being Spider-Man, were erased by Doctor Strange.
