The Watchers

In the comics, The Watchers were one of the oldest species in the universe. And, without interfering, they accumulated all existing knowledge, and were capable of extraordinary feats that dwarfed anything we’ve seen to date in the MCU. Guardians of the Galaxy: Vol. 2 proved that they do exist in this shared universe.
Of course, Kevin Feige said that the Watchers were part of the 20th Century Fox deal, so the characters were available for both studios to use. But we believe – and hope – that there was more to this than just a simple sharing of characters.
The fact that Feige hasn’t revealed what will happen after Phase III makes us wonder whether this deal involved other Fox characters. We can’t bet on it, but maybe this was the first hint that the Fantastic Four (or, at least, some of their most well-known enemies) will make an entrance into this shared universe.
