Henken, a ship captain in the AEUG is first seen in command of the Argama. He works closely with Quattro Bagina and AEUG founder Blex Forra. A tall, burly, jovial and good natured man, he nonetheless takes his job seriously and even turns over command of Argama to Bright Noa, acknowledging Bright's professional experience. Henken subsequently transfers to the Irish-class battleship Radish. Henken is attracted to Emma Sheen and Emma shyly but good naturedly reciprocates the affection somewhat.
