The Death Rider-class was a type of starship built by Section 31. Only four ships of this class were ever created, with each ship named after one of the Four Horsemen of the Apocalypse. (Dimensional Prophecy of Zohar) They were built using the same material as was used to create the Thanatos Weapon Mech. Each ship was equipped with a special energy beam that could connect with the Alien Obelisk Sol-Sirius Network.
