History
Henri Ducard was a skilled assassin wanted in many countries. Upon meeting Felicity Strode (an assassin hired to kill him), the two fell in love and married, having a child named Morgan. Though he was away often, he tried to teach his son as much as he could about the family trade.
Upon returning home, he discovered his son had killed his wife. He was informed of her true identity, choosing to take Morgan with him and train him formally in the ways of assassination.

Later in the series, it is revealed that Ducard is largely amoral, working for criminals as often as he does the law. He deduces Batman's secret identity, but keeps it to himself, thinking as he leaves that Batman continues to exist because true criminals realize that he distracts the people from the greater crimes by his public battle against lesser crimes.
Ducard was hired to assassinate King Snake. He notified Tim Drake of laundered money sent into Gotham.
