 The major conflict between Scar and the State Alchemists is based on Hiromu Arakawa's own background when she lived in Hokkaido, as her ancestors conquered the land belonging to the Ainu people, but some of them were Ainu themselves.This is represented in Scar's revenge against State Alchemists as he ironically uses alchemy like them in order kill them despite being a taboo for his religion.As a result, Arakawa comments that rather than being a common "evil antagonist", Scar's character resulted from several catastrophes that occurred in the Ishvalan Civil War and such a label should be avoided.
