Tumak was a young Skrreean male and the son of Haneek. They were among a large group of Skrreean refugees who arrived at Deep Space 9 in 2370. Tumak was a belligerent and ill-tempered young man. He attacked Nog after the young Ferengi sprayed a foul-smelling liquid on him as a joke. Tumak was played by actor Andrew Koenig, son of Walter Koenig and Judy Levitt.
