While James Gunn played coy on when the Kronans will appear in the MCU again, it’s already been confirmed that at least one of them will appear later this year in Thor: Ragnarok.
Whether or not other Kronans will appear in Thor: Ragnarok remains to be seen, as does if they’ll show up in another cosmic-centric MCU tale, like Avengers: Infinity War or Guardians of the Galaxy Vol. 3.
Performed by Thor: Ragnarok’s director Taika Waititi through motion-capture, the MCU’s Korg is one of the few characters who will befriend Thor on Sakaar, and he’s described as being funny and having a “light soul.”
The main event of this detour will be Thor going head-to-head with Hulk in the gladiator ring, but one of the other aliens Thor will encounter on that world is Korg, arguably the most famous Kronan from the comics.
