Did you watch Avengers: Endgame closely, I mean really close. Because if you haven’t, here’s a jaw-dropping easter egg that you much know, exists in the Endgame’s final battle between the Avengers and Thanos. Avengers: Endgame Secretly Introduced Nova to the MCU.
The presence of Howard the Duck in the battle sequence was seen clearly, but then another character also was present in the line up that no one noticed. Richard Rider was also seen as Nova. This is what Joe Russo had to say about it,
Look closely at that scene again and you will see. You will see Richard Rider in the background of the shot. Easter egg
Fans have implored for Nove to be added to the Marvel Cinematic Universe and it really happened. Nove debuted his first appearance in MCU. For those who have little to no knowledge about Nova, let me brief you about him.
Right in the beginning of Avengers: Infinity War, Thanos had already acquired one of the infinity stones, which is the Power Stones, meaning he destroyed Xandar before acquiring it. The Guardians of the Galaxy left the stone there in their first film and since then all the events happened at Xander were off-screen. Coming to the story of Richard Rider in the comics, he inherits power from the Xandarian Worldmind after becoming the lone survivor of Xander. He turns into Nova when he shares the power of Nova Corps in combination with Xandarian Worldmind.
Now Nova is connected to Guardians and we have no idea whether he was also snapped to dust or survived the snap of Thanos. To me, most probably he survived because that forms a good story to explore for a standalone movie for Nova. Marvel Studios president Kevin Feige said,
Nova is… if we have a big board with a bunch of characters that have more immediate potential, Nova is on that board. Because of the connection to the Guardians universe, because there are more than one examples to pull from in the comics that are interesting. And you’re absolutely right, he was in the earliest drafts of the [Guardians of the Galaxy].
There is definitely going to be a movie where Nove plays an important role, if the movie takes place before the events of Avengers: Infinity War, there are chances of Thanos coming back on screen, the destruction of Xander might be a part of the movie to show how Richard Rider becomes Nova and his plans to Avenge the planet. Marvel might tap the 5 years gap between both snaps of Thanos and Hulk, where Richard Rider might have his character development into a superhero.
