Tom Hiddleston is returning for <em>Avengers: Doomsday</em>, and a recent bit of fan art imagined Loki and Robert Downey Jr.'s Doctor Doom having a standoff in the Marvel Cinematic Universe crossover. While its plot remains a mystery, given Loki is now the keeper of the multiverse, and the cast itself points to a multiverse adventure, it does seem likely that Doom might be after Loki in the hopes of inciting a multiversal war. Plus, with there being comic book history giving precedent for this, it would be interesting to see what a fight between the two could look like. Hopefully better and more exciting than his quick offing at the hand of Thanos in <em>Infinity War</em>.
