The Morgue was the general name for a Welsh series of robots that competed across three UK series of Robot Wars and two series of Robot Wars Extreme. Although taking a variety of weapons and sizes, the robots generally shared the same basic design; a yellow barrel shape, enabling it to self right by rolling over. After fighting in The Fourth Wars under its original name, The Four Horsemen fought in Extreme 1 with Mega Morg, before entering The Fifth Wars, and Extreme 2 (also failing to qualify for The Sixth Wars) with Mini Morg. The team reverted to the name Mega Morg for The Seventh Wars.
