Thanos will destroy Asgard
For The Avengers 3, it looks like we will get Thanos as the main villain. Most fans are guessing this and are pretty sure this is where the films are leading to. Thanos is due to appear in Guardians of the Galaxy and he may get to demonstrate his powers to the audiences for the first time. He will not however have his weapon – The Infinity Gauntlet.
Thor 3 is due in Phase Three, likely in 2017, and this will probably be the final Marvel film before the third Avengers. In order to show Thanos’ power, he should be shown to destroy Asgard. As we saw in Thor, The Infinity Gauntlet is safely locked up in the relic vault in Asgard. If Thanos is to utilize the power he will need to get hold of it. It would be great to demonstrate how powerful the character is by destroying an entire world that we have seen a lot of in both Thor movies. Having an entire realm destroyed by a villain would be a good reason to ‘Avenge’.
