Guardians of the Galaxy Vol. 2 introduced the Watchers in a particularly memorable scene that simultaneously confirmed a popular fan theory that Stan Lee has played the same character across all of his Marvel Cinematic Universe cameos. Now newly released concept art from the film offers a glimpse into the evolution of that sequence.

Character designer Michael Kutsche revealed the image on ArtStation, where we see Lee's character dressed in an astronaut suit and holding court with the group of Watchers. In the movie, the beings appeared in a quick scene in which Rocket Racoon, Yondu, Groot and Kraglin race to rescue Star-Lord from Ego.

The Watchers also appeared in the post-credits, where, bored with Lee's stories about his adventures on Earth, they walk away, leaving him wondering how he'll make his way back
