Bugs Bunny could wield Mjölnir and nobody can tell me otherwise.
I was sitting there scrolling through TikTok the other day — as one does — when I came across this discussion of which fictional characters from ANY universe could wield Thor's hammer, Mjölnir.
In case you forgot, Mjölnir can only be wielded by someone who is "worthy." What exactly that means is kinda nebulous, but the only other character in the MCU who has been able to pick it up was Captain America, and that was only once we got to the events of Endgame.
Of course, several characters have wielded Mjölnir in the comics, including a couple of DC Comics characters: Superman and Wonder Woman.
