Adam Warlock is another character teased via Easter egg in the Collector's vault. Or, at least, the cocoon that he protects himself in was. Adam Warlock's appearance in the Guardians sequel is the one that makes the most sense. Not only because we've seen his cocoon in the Collector's vault, but because he's one of the most well-known Guardians members outside of the usual five, and is usually in possession of one of the Infinity Gems, which are being desperately sought out by Thanos. Now that the Collector's museum has been blown to smithereens, it's safe to assume that some creatures and beings trapped in there escaped. Could Adam Warlock have been one of them? We sure hope so.
