The other night, my brother and I fell asleep watching Guardians of the Galaxy. It's a family favorite. But the next day, we both thought about the missing Easter egg. It was said to be the biggest of them all.
The Beta Ray Bill rumor was probably my favorite, because even I believed it was him! But my brother and I started spit balling and brain storming. The red cape/cloak looked eerily Asgardian. We thought, maybe it could be Thor? What if Guardians of the Galaxy took place after Thor: Ragnarok? Could this also tie in the Guardians with the Avengers?
No, that's too tangled up. But there is one Asgardian it could be. Odin.
For those of you who saw Thor: The Dark World. You gazed upon Loki in all his glory. The Would-Be King sitting atop the throne of Asgard. Although he may look like Odin, he is not the All-Father. So where is he?
I believe that Odin was being held within Taneleer Tivan's "Collection".
If you call folly on my belief, then I must plead that you listen.
In the mid-credit scene of Thor: The Dark World, Lady Sif and Volstagg deliver the Aether/Reality Gem to Taneleer Tivan the Collector.
Now, what better place to keep a weakened Asgardian King than the largest collection of exotic beings and objects that resides in Knowhere. I mean, if that is not already a mouthful. Then this will be just desserts.
Not only would Taneleer's collection and location be an excellent place. But the Aether/Reality Gem would be the perfect price to bribe the Collector to hold Odin within his vault.
All in all, I believe that the last hidden/missing Easter egg for Guardians of the Galaxy is Odin. There have been as many possible theories thrown around in this house, but the science points to Odin.
Let's hope James Gunn gets this. Maybe he can confirm or deny.
