Trajok

From Memory Alpha, the free Star Trek reference

Trajok was a wrestler, specializing in the Galeo-Manada style. He was a member of an unnamed species.

In 2370, he taught Jadzia Dax the technique while visiting Deep Space 9. Afterwards he departed for Calondia IV, but promised Dax a rematch when he'd return the next week. (DS9: "Playing God")

[edit] Background

Trajok was played by Chris Nelson Norris.

The costume worn by Norris as Trajok was auctioned off in the It's A Wrap! sale and auction.
