SPOILER WARNING: The following article contains potential spoilers for Thor: Ragnarok, in theaters November 3.
Marvel has big plans for the cosmic side of the Marvel Cinematic Universe, and a new Thor: Ragnarok Funko figure seems to add plenty of fuel to the speculation fire, with a possibly huge spoiler.
In the description for this toy (via MCU Exchange), Jeff Goldblum's Grandmaster is described as a "Celestial," forming a direct connection with Kurt Russell's Ego the Living Planet from Guardians of the Galaxy Vol. 2. Considering that the Grandmaster and Collector are supposed to be related, it would seem that we have three confirmed "Celestials" in the MCU.
Of course, things are different in the comics, because the Grandmaster, Collector, and Ego are all Elders of the Universe, rather than Celestials. The Celestials are god-like beings who have the power to experiment with life across the universe.
Regardless of what Marvel decides to call them, it is clear that Marvel is planning something big with these entities -- but if they continue to play a role in the Guardians of the Galaxy film series or show up in Avengers: Infinity War remains to be seen.
The Grandmaster will make his film debut on November 3, 2017. Director Taika Waititi’s Thor: Ragnarok stars Chris Hemsworth as Thor, Tom Hiddleston as Loki, Cate Blanchett as Hela, Idris Elba as Heimdall, Jeff Goldblum as Grandmaster, Tessa Thompson as Valkyrie, Karl Urban as Skurge, Mark Ruffalo as Bruce Banner/the Hulk and Anthony Hopkins as Odin.
