When The Avengers ended, and after the team beat the invading aliens, the final cut scene went into outer space where the villain who orchestrated the entire attack plotted his next move. That villain was a mystery to non-Marvel Comics fans, but most comic readers recognized him as Thanos.
Comic fans automatically assumed that would make Thanos the villain in The Avengers 2, as well as in all probability The Guardians of the Galaxy movie, since Thanos is the creature who raised Gamora and the being responsible for the death of Drax the Destroyer’s family on earth.
However, not only will he not be the main villain in Guardians of the Galaxy but he also looks to not be in line as the villain for The Avengers either. I would assume that he will be at least partially responsible for what happens in both movies, but he won’t be the bad guy in them.
Joss Whedon, who knocked it out of the park with The Avengers, said in a recent interview that Thanos is part of his long-term plans at Marvel.
“Well, Thanos is more powerful. He is so powerful; he is not someone you can just trot out and punch him,” Whedon said. “Like he did in the comics, you want him threading through the universe and to save the big finale for the big finale. He is definitely a part of what I have got going on. The thing about The Avengers is that they are very powerful but not very stable. So, there will definitely be some people that will shake them up in the next installment.”
Marvel head honcho Kevin Feige said before that adding him to the closing credits of The Avengers was setting the groundwork for using him later, much like adding Sam Jackson to the end of Iron Man did as well. This is smart, because Thanos is a bad ass and if he heads out to fight The Avengers next, what will top that?
I’m thinking we get something like The Masters of Evil in the next movie and then build to Thanos for the big third one. I’m also holding out for an Ultron appearance, because they didn’t bring him back to Marvel now for nothing. Could the groundwork for that be set up in Ant-Man (Hank Pym, the first Ant-Man invented Ultron)?
