I would say Zombies because they lose body parts when hit and they have great sounds
Most of the enemies fall apart if you hit them with a weak enough weapon i.e. because it takes more hits, though this took me years to realise as I always fought the Pumpkin for example with the throwing axe (which if done right, instant kills them).
Oh and yeah, I vote Pumpkins Wait...... where is that option? aww Or the Zombie Sailors come to that.
Gods, there are octomators! They're really awful and beautiful.) The most dangerous, to my mind. Their damage is 40, they can control your headless body (taking your energy) and keep other corpses. Besides, their appearance implants strong (good) feeling, especially for me.) These big heads and fat tentacles ...
I personally felt MediEvil 2's enemies were hit and miss just like its levels. I'd have to go with the vampires because they were, by far, the most interesting in terms of design and gameplay mechanics.
I think I personally like the Zombies since they're so easily defeated and lose body parts if you hit them with the small sword. The Renfield is also a favorite because of the weird and funny noises they make.
The Octomators are the most frustrating enemies in the game, especially in the Sewers, but they're also great exactly because they're so challenging to defeat. The Regal Zombies are also very interesting enemies from a gameplay mechanics' perspective.
