Marvel Studios reveals that the versions of Thanos that appeared in Avengers: Infinity War and Avengers: Endgame have different names. When audiences first saw The Mad Titan in the mid-credits scene for Avengers in 2012, the purple monster was threatened by something different from what the Avengers had or should have faced.
After several years of fans asking why he has not been as active in getting the Infinity Stones, he came back with a plan to achieve his ultimate victory. He has conquered many worlds, collected all six Infinity Stones and wiped out half of all life throughout the universe.
Satisfied with the work, he destroyed the stones and did not fight back in his weakened state when the Avengers arrived. When he died there in 2018, Avengers: Endgame’s time travel story allowed him to return to a different version of Thanos. This take on the younger version was amidst victory, and he learned that one day he would achieve his goals.
Through this storytelling mechanic, Avengers: Infinity War and Endgame presented two different versions of Thanos to the audience. In the newly released book The Art of Avengers: Endgame, the concept artist Wesley Burt revealed that “he was always known as the Warrior Thanos, as opposed to the Philosopher Thanos in Infinity War.”
Though Thanos was never addressed by these names in the films, it does describe the different moods he had in each film. Thanos arrives at Avengers: Infinity War to achieve his goals and knows exactly what to do and doesn’t waste a moment.
Once he completes his tasks, he immediately moves on to the next, rather than lengthening the ongoing matches. This is in contrast to Thanos from 2014 in Avengers: Endgame.
Here he approaches the threat of the Avengers directly from a major battle and has the mentality of those warriors throughout the film. This Thanos has seen the future and knows that he has won and believe his actions to be inevitable and acts accordingly.
These differences and the fact that Marvel Studios understands the two versions of Thanos will be the key to remembering the way forward. Although the Philosopher Thanos is dead, both versions of Thanos are likely to return.
Movies like the Eternals which is set in MCU’s past may show a younger version of the Warrior Thanos, but the Nova film that sees Xander being destroyed as Richard fight can see the Philosopher Thanos getting his first Infinity Stone. Meanwhile, theories that suggest Warrior Thanos is not actually dead are more likely to come true. We don’t know when the Warrior Thanos turned into the Philosopher Thanos, but we’ll learn about it in future MCU stories.
