Please give me an anime!?

You definitely need to watch Fullmetal Alchemist, it leaves you wanting more, it's Shonen, it's full of action, a lot of plot twists, you don't need to wipe your memory to watch it again (at least I didn't need to) and even though it may look a bit funny, the story is really serious and dark. Oh and for the record, the main character looks a little like Allen Walker.
