Naruto and Naruto Shippuden,because it is about a boy who was abandoned by everyone and wants to prove everyone that he isn't like Kyuubi(Nine Tail Fox)a monster that he carries inside of him. His proving it with difficult and hard work, risking his live on every mission to save friends and those who are lonely as he once was. There is a lot of fun and I love Naruto.
Sailor Moon, because it taught me the importance of true love and friendship. Plus the battles are so epic and the characters rock! and i love all of the theme songs and character songs too. I should add the live action was really good and the manga rules!
Durarara!! because it follows multiple characters which makes for a great storyline and its action-packed, thrilling, awesome and even has some romance
My favorite anime is Fullmetal Alchemist (both versions). FMA is my favorite because it told me a touching emotional story, plus the characters are just so lovable.
