10 Most Believable Avengers 4 Fan Theories
5. Unlikely Back-Up Is Coming
The Theory
When it comes to fighting Thanos again, the survivors are going to have an almighty battle on their hands made even more difficult by their depleted numbers. What they need is reinforcements, and according to one theory, they're going to get them from an unlikely source.
The theory suggests that Thanos' snap will be deemed heinous enough by even the universe's villains to drive the survivors together - unified in an "enemy of my enemy is my enemy" sort of deal. So we might see Ravagers, Kree... maybe even Skrulls coming to the assistance of the heroes when the time comes.
Why It's Believable
It's unlikely that even villains will simply sit back and accept that Thanos has killed half of their number, so it makes sense that they could put aside their differences to all focus on re-establishing true order. Before, presumably, picking their weapons up again and going back to their day jobs.
