Fullmetal Alchemist
Soul Eater
Death Note
(For some) Hetalia

That Depends are you looking for a certain Genre and are looking for an anime to be in a specific language? (like English,the original Japanese etc.)some anime that come to mind are..Fairy Tail (which is a very funny anime!,and it comes in dubbed also),Kuroshitsuji/(also known as Black Butler in the dub) is a very good anime too!,Fullmetal Alchemist is a good one too...it can be a really sad anime too..Azumanga Daioh is an extremely funny anime same can be said for Lucky Star (though it's a bit more random),Fruits Basket is a cute anime to watch also,then there's also The Melancholy of Haruhi Suzumiya! that's amazing too! Ouran Highschool Host Club is also a great anime! it's really great!..One Piece,Katekyo Hitman Reborn(It's Only in Japanese though) and finally InuYasha..and those are the only anime I can think of now,anyway hope I helped!

Rosario + Vampire
Mushishi
