Dämonfeuer (an elderly sick one gave Nick a very hard time)

Mauvais Dentes (Needed 2 Grimms to take down)

Excandesco (Can't even get near)

Wildesheer (no explanation needed)

Matança Zumbido (without ear paste, would be electrocuted)

Koschie (radioactive touch, plus pretty strong and insanely hard to kill)

Huntha Lami Muuaji (acidic touch)

Vulpesmyrca (almost killed nick)

Siegbarste (Oleg would have killed Nick if Juliette hadn't come with the clutch save)

That's about it.
