–Emily Zhang to Frank Zhang
Emily Zhang was a Canadian soldier who died during the war in Afghanistan, saving several comrades' lives in the process. Since she was such a great soldier, Mars, the Roman god of war, admired her and she became the mother of a Roman demigod, Frank Zhang. Emily was a major part of Frank's life, and she taught him his ancestry when he was a child. She was a witness to the revelation of Frank's firewood, and knew about the various weapons in the mansion. According to Juno, Emily was somewhat foolish during the war, thinking her powers could save her and her team. This comment understandably irritated Frank.
- Emily had a habit of using several greats in a row when talking about the family's ancestors, while poking Frank's belly.
- Emily is the only Greek legacy known to have had a relationship with a Roman god.
- According to her son Frank, Emily looks like the goddess Iris.
- Emily is the only known mortal parent of a demigod to not be fully human, being a descendant of Poseidon.
