Every Marvel Villain The MCU’s Main Universe Has Teased But Hasn’t Used Yet

There’s a wide variety of different Marvel villains who have been teased in the MCU, but not fully used. Across the franchise’s 15-year legacy, some of these foes were teased as far back as the MCU’s very first year while others have only recently been hinted at in more current projects. As such, the eventual debut of some of these teased supervillains will hopefully happen sooner rather than later as the MCU keeps getting bigger (especially with the emergence of the multiverse).
