4) Adam Warlock
Cosmo isn’t the only character hidden in the Collector’s collection. A bonafide Marvel superhero can also be found if you keep your eyes open.
In both Thor: The Dark World and Guardians, a glowing cocoon can be glimpsed at several points. Once they see it, fans will recognize this as the cocoon of Adam Warlock – a hugely powerful hero based in outer-space. Intriguingly, in the aforementioned post-credits scene of Guardians, you can see that the cocoon is now open…
As we said in our “10 Awesome Moments of Foreshadowing in Marvel Movies” list, this is surely more than a quick nod to the comics character and is in fact actually setting Warlock up for an appearance in the MCU further down the line.
The character is a major part of ‘The Infinity Gauntlet’ storyline in the comics, so expect to see Adam Warlock turn up proper in Avengers: Infinity War, or perhaps Guardians of the Galaxy Vol. 2.
