"Welcome to our special Grudge Match edition of Robot Wars. Over the course of the last two wars over 150 teams have competed and things have turned a bit nasty. Some people haven't been happy with our Judges' decisions, others have made enemies and wanna sort them out, some just want revenge and hey, if people wanna fight who are we to stop 'em. Over the course of the next half-hour prides will be dented, scores will be settled and grown men will be reduced to tears and we're gonna love it!"

After the main competition of Robot Wars: The Second Wars, a special episode was shown featuring a number of Grudge Matches. This gave robots the chance to settle old scores and also allowed robots that did not feature in the main series a chance to battle in the arena.
