Fullmetal Alchemist has quite the complex story to it, often branching out into different side stories. It begins with past events heavily impacting the plot and characters and always giving off the feeling that there is more than meets the eye going on.
The story heavily revolves around the two young Elric brothers, Edward and the younger Alphonse. Their journey as extremely young state alchemists has more twists and turns than a tin of spaghetti. The events that transpire on their story heavily test the bond of brotherhood and more than often question their morality. When it comes to alchemy and other types of magic there are often very dark and immoral ways to use it, as was explored in this series.
With many large countries explored in the series it is understandable that there is a vast cast of characters encountered along the way. But how much did you pay attention to them? Bet you can't name all the following characters!
