The Manic Mutants also entered Series 5-7 with the more successful Shredder, which reached the Heat Final in Series 6, but also lost in the first round in Series 5 and 7.
Manic Mutant was a four-wheel drive, box-shaped robot armed with a set of lifting prongs at the front which could lift 100kg, and a bludgeoning spinning disc at the rear which featured spikes on its face. The robot was armoured in stainless steel obtained from a roof rack, and most of its internals were sourced from a forklift. Manic Mutant cost £265 and took a month to build.
In its first round battle, Manic Mutant faced Gravedigger. It quickly charged at Gravedigger in the opening moments, but Gravedigger swerved out of the way. The two robots circled each other until Manic Mutant got behind Gravedigger and attempted to push its opponent. However, Gravedigger pushed Manic Mutant backwards. Manic Mutant drove away and charged again at Gravedigger, bashing into Gravedigger's side. Manic Mutant then drove up onto Gravedigger's wedge and was flipped over onto its back, eliminating Manic Mutant from the competition.
