Avengers: Endgame - 11 New Heroes It Could Introduce

2. The Eternals

The Eternals was a surprise inclusion for Marvel's Phase 4 plans, but it seems as though the studio are very keen on the project, with filming set to commence later this year. Given Marvel's reported enthusiasm for the project, it wouldn't be at all surprising if the Eternals - or at least either one of Ikaris or Sersi - were to appear in Endgame, and according to rumour, that may just be the case.

Daniel R claimed back in November that two Eternals - Piper and Sprite - were to appear in the post-credits for either Captain Marvel or Avengers 4, and with Captain Marvel having passed with no Eternals cameo, that leaves Endgame as the only candidate for them to appear.

It's worth mentioning that this is all still rumour, as well as the fact that (as far as we are aware) no one has been cast in any given role for the upcoming Eternals film, but that doesn't mean it won't happen. There's a bit of a competitive nature to the Eternals film, with DC pressing ahead on New Gods - it too a Jack Kirby creation - so it could be possible that Marvel are keen to beat their competitors to the punch.

Either way, it'll be interesting to see how Endgame's post-credits play out. One would suspect it'll have something to do with Far From Home, or potentially even Black Widow, given it's likely to be the first Marvel film of 2020, but if Marvel are as determined to make the Eternals a key part of Phase 4, it makes sense to tease their arrival as soon as possible.
