A leader of Atlec in The Outrageous Okona who demands that the Enterprise surrender Thadiun Okona, believing the freighter captain has made his daughter Yanar pregnant.
Debin is a senior figure of Atlec, one of the twin planets of the Coalition of Madena. He appears in the second-season episode The Outrageous Okona, set in 2365, arriving in an outdated ship to confront the far more powerful Enterprise.
He insists that Thadiun Okona, whose cargo vessel the Enterprise has been repairing, be handed over to answer for the condition of his daughter Yanar. At the same time Kushell of the rival world Straleb arrives with a different charge, and the two men quarrel as fiercely with each other as with Picard.
Okona's seeming offer to marry Yanar brings out the truth: her lover is Kushell's son Benzan, and Okona only carried messages between them. Debin is left to argue with Kushell over where the young couple will live.
