my fave FMA chars are!
The crimson alchemist- I love his character because of his alchemy name and what he does. Its very unique and genius for someone to be able to take anything he wants and turn its properties into thing that become unstable and explode! He was a refreshment for me from the other alchemist who use whatever they have around them stone/steel ect.
Brigadier General Basque Grand(the iron-blood alchemist)-Although he was only in the show for a short amount of time i loved his alchemy just a tank person made of guns haha. Sad i did not get to see more of him i think he would have been a great character to keep longer.
