1. Scary Terry – His name says it all, he is one scary creature that we see in season 1. He has the ability to torture people with their worst fears. The funny part of this character is that this is how he makes a living. Yes, you heard it right, this is his job.
2. Snowball – Our next creepy character is Snowball. We do feel for Snowball because he has to deal with being very intelligent but is still a dog. He might deserve sympathy but what he does is still horrible so he gets a spot on this list.
3. Evil Morty – The evil version of Morty is definitely one of the most terrifying creatures of the whole show. Throughout the show, we see hints that he is planning something very evil for Rick and Morty. Also, the eye-patch is creepy.
4. Rick Sanchez –This was a hard one to put on the list. He causes a lot of sympathy with the viewers but then again he causes a lot of suffering to everyone that is close to him. There is no doubt that he is evil, but he is also very much human.
5. Supernova –a classic tale of a fallen angel. She starts out as a real superhero, but as her story moves along she becomes weaker and weaker morally. In the end, she’s prepared to murder not only her ex-lover but also Morty, who had nothing to do with anything.
6. Monster Beth – This creature was actually a result of what someone imagined. Jerry to be exact, her own husband! She might look scary, ugly and grotesque but she’s also intelligent as she manages to escape from the laboratory where they made her.
7. The Devil – Almost didn’t end up making the list because of his mostly businessman behavior through most of the episode he still does a messed up thing. Summer gets left with nothing because of him and that is enough to get a spot on the list, especially after she stops him from killing himself.
8. Krombopulos Michael – There is no question he is evil, but then again he is also very likable. That being said we can’t forget that he is still a brutal, cold-blooded murderer. So, he gets a spot!
9. Fart –One of the most, if not the evilest one of all. What he wishes to do is destroy all life, pretty evil right? The way he plans to do it is pretty horrible too. Not to mention tricking Morty into being his friend by pretending to be the victim. Evil!
10. The eyehole man – Such a horrible creature. What even is it? Plus the whole beating people till they die just for buying something commercial. Cruel and sadistic.
