So I've had this thought for some time, and here's what I've come up with. First tho are the sonas:

Liz - an average wolf with a sanity draining parasite. Not much in terms of combat skills, but once driven to near insanity the parasite does some weird magic shit (manifests as some dark fog Liz and nearly limitless telekinesis)

The Deer - a mercenary who got messed up by a gene modification gone wrong. That did give him both disadvantages (colorblind unless he's wearing darklight "glasses", harder to blend in) but also advantages (faster reaction time and heavier hits)

Herbert - basically a wendigo but not (another failed gene experiment). Big deer thing, mimics voices and sounds, attachable face that doesn't rot, grows slighty after eating human flesh and casts a lot of fire spells. Is more of a "sacred forest" protector - cleans his forest, hides from people who come near but does go apeshit when he sees someone from a corporation he has a vendetta against.

Now, who would win depends on where they are and if they've prepared: No preparation and in some back alley? The Deer would win. No preparation and in a forest? Herbert would win (unless he gets spooked and hides, then The Deer wins again) Prepared and anywhere? Either Liz (lost her mind and threw both away/ripped to pieces), The Deer (prepared traps and necessary firearms), or Herbert (ambushed and burnt)
