The name combines two references: "Odyssey" for the long, epic journey of exploring the entire Marvel canon, and "616" for Earth-616, the designation used by Marvel Comics for its main fictional continuity since the 1980s. Unlike the "MCU" acronym, the "616" reference is part of decades-old comic-book lore and is not a registered trademark.
