Hademar Zemo was the second Baron in the Zemo Barony. Hademar was greedy and eagerly awaited his father's, Harbin's, death so he could become the next Baron. Soon after Harbin's death, Hademar's twelve-year old son Heller Zemo started a coup and had Hademar slain by his guards at his inauguration. 
According to Helmut Zemo, Hademar was little more than a footnote in his family's history.
