Both series deal with mature teenagers going through a great struggle to achieve some bigger goal, going to particular adventures, fighting for their lives. All the hardships they go through, together with friends and comrades, is in both series almost similar. Sometimes the characters are a bit more childish in FMA², but both series deal with alot of the same elements.
