In Japan, they came out with three mini FMA OVA's
The first OVA would take place in the afterparty of the Conqueror of Shamballa movie
The second OVA would take place 50 years later... Current day with the grandchildren of Ed and Al, and um... Winry.
The third OVA is an all out battle between the state millitary and the Homunculi, there is two parts. Interms of action this one is rather 'cool'
