For the past few years we've watched Thanos' story play out over the course of several films. Through agents like Loki and Ronan, he has tried to gather the Infinity Stones for himself, only to be thwarted by Marvel's heroes.
With the release date of Avengers: Infinity War growing ever closer though, Thanos looks poised to take matters into his own hands. The Mad Titan is no slouch and, with the power of the Infinity Gauntlet, he would be almost unstoppable. It's going to take something pretty special to save the day.
Now, details on Infinity War are pretty sparse at the moment and all we really know about it is that it will see every Marvel hero and their mother teaming up to fight Thanos. However, who needs facts when you have rampant speculation?
There are a number of potential ways that Thanos could be beaten, involving plans that take inspiration from the comics and ideas already hinted at in the movies.
Admittedly, some are more plausible than others (and one might not be a super-serious suggestion), but at this stage it's just fun to speculate and see what kind of crazy ideas we can come up with.
