This sort of the opposite of the blogs which ask what tyoe Wesen would you like to see in the future, my question is what Wesen that have already appeared, would you like to see as the main agonist of an episode (possibly again)? Granted many Wesen make recuring apperances, often when you don't expect it, but appart from Hexienbaest, Blutbaden, Reapers and Schakal few are the main agonist of multiple episodes.
Personally I would like to see Dickfellig, as they look cool and were under used. Damonfuer as there awsome and Lausenschlange as they need expanding. What Wesen would you like to see have a rematch with are favourite Grimm?
