hou Tucker, the Sewing-Life Alchemist (綴命の錬金術師, Teimei no Renkinjutsushi), was referred to Edward Elric by Colonel Roy Mustang in Chapter 5 when the Fullmetal Alchemist was in need of a bio-alchemist whose research notes might hold a clue to restoring his and Alphonse's bodies. Tucker had gained a bit of notoriety and earned his State Alchemist's License two years prior to the series by producing a chimera capable of human speech.
