Yeah, it's a bit old and can be tough to find, but it's worth it (I only read a few issues of the manga, but the beginning is pretty faithful, so I assume the whole series was too). I think I actually lucked out and found it on Crunchyroll, but I don't think it's on there anymore.FMA: Brotherhood
Death Note if you haven't seen it.
You might like Naruto Shippuden. I think it's ending soon so it would be a good time to start. A lot of people hate on Naruto but it has a lot of great moments (I suggest skipping the fillers though)
Kaze no Stigma I only watched a few episodes of but it seemed like an interesting anime. Lots of action.
There is a MÄR anime?
I loved the manga.
