Fullmetal Alchemist Role

Sasaki plays Sig Curtis, the towering, soft-spoken Dublith butcher married to alchemy teacher Izumi Curtis, across both the 2003 Fullmetal Alchemist series and the 2009 Brotherhood adaptation. Sig is a supporting but memorable figure who houses and toughens up the Elric brothers during their apprenticeship years, and Sasaki held onto the part in both continuities rather than being recast when the story was retold.
