Guardians of the Galaxy Vol. 2 wasn’t exactly overflowing with Marvel Cinematic Universe references, and that’s entirely OK. Director James Gunn was more focused on making it a stand-alone sci-fi romp, an approach that was a refreshing change from the “just wait until you see what happens in the next movie” philosophy of past MCU installments. That said, it wasn’t completely separate from the rest of the universe, indicated by a handful of subtle connections. Here’s what we saw.
In Marvel’s comics, the Celestials pop up all the time, appearing as godlike beings as eternal as the universe they reside in. The first Guardians of the Galaxy movie even featured Knowhere, a planet colony formed inside the skull of a dead Celestial. In Guardians Vol. 2, Ego the Living Planet makes an appearance, retconned by the MCU as Peter Quill’s father. Odds are, this isn’t the last we’ll see of this ancient race either.
