Wesen are the things nightmares are made of, and Grimm is filled with them. Over the past five seasons, we've seen every creepy crawler you can imagine come to life. Some are classic incarnations, while others are modernized versions with a twist. Either way, they're unique creations that aren't easily forgotten.
Only the most innovate monsters are on my radar. With over 100 episodes in the can, it wasn't easy to narrow it down. But the cream always rises to the top. Some Wesen are more horrifying than others but their look gives them a competitive edge. Does it shoot fire? Can it glow in the dark? Is venom involved?
With so many to choose from, I've ranked the best of the bunch, starting with what some may consider an unlikely choice.
What is your favorite Wesen? Did it make the list?
30. Hasenfussige Schnecke (Season 5, Episode 6)
The Hasenfussige Schnecke is a fish-like blob that's known for its cowardice. They're fairly emotional creatures whose body's are covered in watery mucus. How delightful!
29. Steinadler (Season 1, Episode 13)
One of many bird-inspired Wesen, Steinalders are known for their superior vision. It's no wonder they look and act like hawks.
28. Seltenvogel - (Season 1, Episode 16)
This Wesen is extremely rare. The Seltenvogel is usually marked prey because of its ability to produce, Unbezahlbar, a golden egg that must be carefully extracted from their throats.
27. Fuchsteufelwild (Season 2, Episode 16)
No, this isn't a Spider-Man villain, although it is inspired by the same creature. The Fuchsteufelwild is a goblin-like monster that loves to play tricks on its victims. They're the Rumpelstiltskins of the Wesen world.

Balams are aggressive and obsessive -- a dangerous combination. They're inspired by the jaguar, with colors ranging from gray to purple to blue.
23. Spinnetod (Season 1, Episode 11)
If you hate spiders, skip this Wesen. Female Spinnetods are fast, agile, and have regenerative properties. They shed their skin every five years and must consume a male's insides to finish the process. Gross.

21. Furis Rubian (Season 5, Episode 16)
Furis Rubian are typically non-violent but are often misidentified as the Devil himself. The red skin and horns might have something to do with it.

14. Glühenvolk (Season 2, Episode 19)
Glühenvolks look a lot like aliens due to their bulbous heads and glowing skin. When females become pregnant, they prey on cows and consume their ovaries. It's their version of prenatal vitamins.
13. Dämonfeuer (Season 1, Episode 14)
Every fairy tale needs a big bad dragon. Dämonfeuers are as old-school they come. Keep your guns to yourself. Their fire breath can melt almost any modern weapon.
12. Murciélago (Season 1, Episode 20)
Murciélagos are batty, in looks and personality. They quickly go from one emotional extreme to the next. You never know what you're going to get. Plus, they're hideous.
11. El Cucuy (Season 3, Episode 5)
There's nothing scarier than a mean old lady. That's why Grimm's take on El Cucuy aka the Bogeyman struck a cord. It's a universal terror.

It doesn't matter how old you are, Krampus is a total nightmare. It's a horrifying alternative to Santa Klaus with demon and goat-like features. He appears at Christmastime, kidnaps bad children, and eats them at his leisure.
