Avengers: Endgame - 15 Essential NEW Rumours & Theories
9. Two Eternals May Show Up
The Rumour
According to the current Scoopmaester General on Twitter (DanielRPK), there's a big secret double cameo in Endgame that fits in with one of Phase 4's big new properties.
He says that the Eternals - who are strongly rumoured to be getting their own movie - are going to appear in Endgame:
On top of that, Thanos will probably then show up in the Eternals movie, which will reportedly be set thousands of years before the MCU kicks off.
Response
Since we know The Eternals are probably coming to the MCU, having them debut in an Avengers 4 post-credits cameo (or in a brief scene establishing a link to Thanos) would make a lot of sense.
It's not like there are many other options for viable post-credits at this stage. Maybe Spider-Man? And it's unlikely we'll only get one.
