If not, this a scan of a poster that comes with the 5th FMA Fanbook. ^^. It's a group picture that includes every character worth remembering, plus a couple additional cameos. (Chimera!Cain? XD) It was so cute that I just had to scan it and share. :3
Also, because it includes *everyone*, there ARE spoilers... but only by showing characters you may have not yet met. It doesn't spoil anything beyond that. :3 And there are no movie spoilers.
