The vessel of the Hunters, which follows Tosk through the wormhole to Deep Space 9 in 2369, probes the station's shields and beams an armed party onto the Promenade.
The Hunter ship appears in the first-season Deep Space Nine episode Captive Pursuit. Tosk, the first visitor from the Gamma Quadrant, has already limped to the station in his own damaged craft and been befriended by Miles O'Brien when a second, larger ship emerges from the wormhole.
It ignores hails and sweeps the station with a radiation scan that lets its transporters cut straight through the shields. Helmeted Hunters materialise on the Promenade, fight their way past Odo's deputies and corner Tosk in a holding cell.
Their leader explains that Tosk are bred to be hunted and that being taken alive is the greatest shame. Sisko feels bound to let the ship take its prisoner home, but O'Brien quietly helps Tosk escape so that the chase, and the Hunter ship's pursuit, can go on.
