This is a birthday present for , commissioned from Reyn Goldfur, of Caves and Critters fame. Sorry about the endless tweaks and revisions! If he posts his original on FA, I'll link to it here.

Merlin has occasionally mentioned that Jinx is her favourite character from her own comics, so I figured that would work well as a present. But Jinx has been depicted in four different forms.
Canonically he is a 15-year-old boy in Random Encounter, and an adult in New Game Plus (where he has become a psychopomp). Outside of that he's also been doodled as a feral fox, and briefly cameoed as an anthro in my own Heads You Lose comic (albeit in grave danger of losing his head).

I was originally going to suggest the artist picked the one they liked best, but I realised it might be fun to depict all of them, in the style of the 'March of Progress' picture by Rudolph Zallinger. So here we are.

Happy birthday, Merlin!
