Earlier this year I binge-watched "Supernatural" on Netflix in three months. Yup, you read that right, twelve seasons in three months. Of course, I loved Sam and Dean constantly fighting demons and creatures but everything changed in season four. That's when my favorite character ever, Castiel was introduced. At first, I was skeptical, because he burned everyone's eyeballs out when they saw him. However, now he is just a friendly angel that just wants to help. Besides Misha being a perfect human being, he also makes Castiel very lovable. Here are twenty reasons why Castiel is and will always be the best character on "Supernatural". Sorry, Sam and Dean.

1. He's clueless.

Castiel is clueless in the best way. Him being an angel, he doesn't quite understand how humans interact.

2. He has an innocent mind.

The things that fly out of Cas' mouth are always surprising. He doesn't understand that some things can be misconstrued as "dirty".

3. He took Dean out of hell.

When Dean magically reappeared in season four both he and Sam were shocked. They didn't know who it was until Castiel showed up and revealed it was him.

4. He's hilarious without even trying.

The above GIF just shows one of Castiel's priceless moments.

5. He's a cutie.

Everything he does is just straight up adorable.

6. He makes mistakes.

Castiel may be an angel but he does make mistakes just like humans do.

7. His love for Meg.

This was the weirdest thing ever but also sweet at the same time. An angel falling in love with a demon, how adorable.

8. He's loyal to the Lord.

God would obviously be Castiel's father and he stays extremely loyal to him throughout the seasons. Even though he has never seen him.

9. He's sarcastic.

When he first appears he doesn't understand when Sam and Dean use sarcasm. Now he's fluent.

10. His unique way of getting rid of someone.

This might be the coolest thing about Castiel. You don't want to get this dude mad.

11. He can be mean when he wants to be.

Again, you don't want to get this dude mad.

12. He gives the best advice.

This was for the apocalypse, but it's great advice for anything.

13. He tries to help.

Maybe Cas should just stick to being an angel.

14. He has unique nicknames.

Even Bobby was shook.

15. He's persistent.

16. He loves Jack.

I thought this was one of the sweetest Castiel moments ever. He promised Courtney he would watch over Jack and I might have cried when they met for the first time.

17. His signature trench coat.

There's no Castiel without the trench coat.

18. He's relatable.

I've never related to anything more.

19. He's honest.

He knows Dean's habits like the back of his hand.

20. He helps protect the boys as much as he can.

What would they do without Castiel? What would we do without Castiel?
