I'm playing this very silly browser game at present, which half of the YouTube creators have been paid to advertise. (RAID: Shadow Legends, but since I'm not being paid to mention them, I'm not going to go into what I like about it?) But I found Grim!



I mean...I can see the resemblance. This fellow's in the Void dungeon. Which also fits.
