A Ligonian nobleman who serves as Lutan's second in Code of Honor, is thrown to the deck by Tasha Yar in the cargo bay and is finally chosen by Yareena as her new mate.
Hagon is a Ligonian who accompanies his leader Lutan aboard the Enterprise in 2364 in the first-season episode Code of Honor, when the ship comes to Ligon II to obtain a vaccine needed on Styris IV.
As Lutan's lieutenant he carries the vaccine sample at the welcome in the cargo bay. When he tries to push past Tasha Yar to hand it straight to Picard, she throws him to the deck. He is also present on the holodeck when Yar shows the visitors her aikido programme, and he then assists in Lutan's abduction of Yar, which under Ligonian custom is counted as an act of daring.
Lutan's scheme to have his wife Yareena killed in a ritual duel fails when she is revived aboard the Enterprise. Her death has ended the marriage, so the lands and wealth remain hers, and she selects Hagon as her new First One.
