Plunderbird 4 is a British heavyweight robot, that competed in the fourth series of Robot Wars, with little success. The team had previously entered with Plunderbird 1, Plunderbird 2, and Plunderstorm, of which only Plunderbird 2 had achieved any success in the arena, reaching the Semi-Finals. Plunderbird 4's weapon is the team's infamous "Slicer Dicer", although the weapon never caused any real damage during the show's run.
