According to o0Crofty0o, who extracted all the models here, the game files are pretty strange. I finished the game twice entirely, and then played every level again at least thrice, for the speedruns, and I don't remember ever seeing Merc in game. Maybe I'm wrong though, but the thing is that there is an HQ model of him!
Anyway, I tried my best to make it look like it was taken from the game itself, with kinda pure light, strong colors and great whiteness. Hope it worked.
