The Chokuzan Warship with the Delta Flyer.
The Chokuzan warship was a ship belonging to the (possibly fictitious) Chokuzans.
In 2377, Q used a Chokuzan warship as a ruse to test the values of his son, Q Junior. Junior encountered the warship after escaping Voyager aboard the Delta Flyer. When Junior refused to give into the "Chokuzan"'s demands for surrender, they attacked the Flyer and injured Junior's friend, Icheb. In exchange for information to help Icheb, Junior surrendered himself to the occupants of the warship, after which it was revealed to have been created by Q. (VOY: "Q2")
