"

Upon arriving in the United States, Victor von Doom met Reed Richards, his future rival. He built a machine to communicate with the dead, specifically his mother, but ignored Richards’ warnings about its flaws, leading to a catastrophic explosion that severely damaged his face.[1] Expelled after the incident, Victor traveled until he collapsed on a Tibetan mountainside, where he was rescued by monks. Mastering their disciplines, he forged an iron mask that permanently bonded to his skin, adopting the identity of Doctor Doom.[1] As Doom, he sought revenge on those he held responsible for his accident, particularly Reed Richards, and successfully led a revolution to take over Latveria.[citation needed]
