This isn't aloud. >.> It's character fights not two different things and if I'm guessing right it's FMA vs Naruto? If so then alchemy needs a transmutation circle except for a few people can use without one to be able to change objects into something else. While on naruto you either have to use hand signs or else just distribute your chakra to change the stuff around you into a jutsu. Get rid of the circle and they can't do anything unless they saw the gate or have a work around like mustangs gloves or armstrong's gauntlet. While naruto's characters can just train to use one hand. >.>
They really can't be compared because they both have dis and advs.
