“Confusion is but the first step on the journey to knowledge” – Beast
The version of Beast seen in The Marvels’ post-credits seems to be voiced by the original X-Men actor Kelsey Grammer. However, this version of the massive blue mutant is fully CGI, moving away from the practical makeup from the Fox films.
Hank McCoy is a leading member of the X-Men and was portrayed by Grammer and Nicholas Hoult previously in live-action. This is the second time that a legendary X-Men character has appeared in the MCU, with the first being Patrick Stewart’s Charles Xavier aka Professor X in a cameo from Doctor Strange in the Multiverse of Madness.
Interestingly, the common thread between the two cameos was that each member of the X-Men was accompanied by a version of Maria Rambeau. In Multiverse of Madness, it’s on Earth-838, but it’s not explicitly stated which timeline is visited in The Marvels.
