The culmination of undertakings that has happened before is wrapped in the third phase of Marvel Cinematic Universe's upcoming movie "Avengers 3: Infinity War" as the members of the Earth's Mightiest are warming up for a battle with Thanos.

But, who is Thanos by the way? It's worth mentioning that this big bad villain has brief appearances on the previous MCU installments - Guardians of the Galaxy and Avengers: Age of Ultron. It took longer time to see the character playing a big role for the reason because, "Thanos poses considerable challenges for the screenwriters due to the immense power he possesses." according to a report from Screenrant.

"I'll do it myself," this is Thanos remarkable line while grabbing his Infinity Gauntlet from the movie's predecessor Avengers: Age of Ultron.  However, there's a twist in Thanos Character. Josh Brolin, the actor playing the character of Thanos spoke with Movieweb in interview and he said, "Mighty Thanos will essentially square off with the Marvel Cinematic Universe's entire roster of superheroes." When asked what particular aspect of the character that made him excited to portray the role, "Yeah: where's the humanity? There are parts of him that are unfounded to me, which will be found. That's all I'll say."

Christopher Markus and Stephen McFeely, the script writers revealed that Thanos is a three-dimensional character. "Yeah, and like any character, we're going to learn about the character, not just as a villain. If you've got the guy taking you through more or less two movies, he can't just be twisting his mustache the whole time."

Scarier and more likeable are expected from Thanos well-rounded character. It seems like an in-depth understanding of his motives in gaining control of all existence and destroying everything is needed from the eager fans.

The full cast list and synopsis are still under wrapped and Thanos' evildoings and hidden motives remains a mystery until the movie will hit the theaters on November 2016.
