Marvel

Theory Briefing
- A viral fan theory holds that Howard and Maria Stark secretly adopted a replacement child, making Iron Man a Victor Von Doom variant in disguise his entire life.
- Believers cite the Endgame reunion scene with Howard Stark, arguing Tony's mother's pregnancy timeline never actually added up.
- A competing version pins the swap on Kang deliberately erasing Doom from the multiverse, with Loki's rise as God of Stories accidentally restoring him.
- Tony's recurring visions of a dark future are reread under this theory as fragments of Victor Von Doom's own memories breaking through.
- Fans are split three ways: the twist deepens Tony's arc, it quietly erases a decade of character work, or Marvel never needed to explain the resemblance at all.
