After setting his presence throughout the early phases of the MCU, Thanos was fully introduced in Avengers: Infinity War. This film revealed his goal to “save” the universe by wiping out half the existence.
Fans find out that Thanos himself is plagued by the loss of his home planet called Titan, which ignored his call to cut the population. But we don’t get to know how Thanos escaped the befell of his planet.
According to Avengers: Infinity War-Art Of The Movie, Thanos was exiled from Titan after he gave his proposition. He was not present at the time the planet got destructed. It’s a major incident in the MCU, as it drives Thanos to obtain the Infinity Stones.
Marvel Studios President Kevin Feige earlier spoke about the importance of Thanos in the MCU.
“Thanos has been lurking in the shadows with a desire to obtain these Infinity Stones, which has played a big part in our other films,” Feige said in Marvel Studios: The First Ten Years. “We’ve introduced the Tesseract, revealed to be the Space Stone; the Mind Stone, which came out of Loki’s scepter and then went into Vision’s forehead; and the Time Stone: the Eye of Agamotto that Doctor Strange wears is an Infinity Stone itself! And of course the Guardians dealt with the Power Stone.
“So these storytelling devices that we’ve seeded into every film will continue to play a part and come together. We’ve been teasing this for six years. That’s a long time to tease something cinematically before paying it off. Thanos has to be the greatest villain in our movies.”
Now that Thanos has succeeded in acquiring all the Stones, he seems unstoppable. Screenwriter Christopher Markus teased how the heroes may defeat him in Avengers 4.
“They’ve been misused by people who didn’t understand their true power. And now that the real master of them, Thanos, has shown up we can see what they actually do,” Markus said. “The problem is, as you can imagine, as you gain control over these things, your story just goes haywire because why are there ay stakes for the man who can control time, space, reality, your mind, your soul and power? He can reset as many times as it’ll take. So you have to build in a lot of bumps in the road or maybe keep one stone away from him for long enough in order for the thing to have any dramatic structure at all.”
