High Quality Content by WIKIPEDIA articles! Sludge is a fictional character in the Transformer toy line and fictional series. Sludge is a slow witted but powerful Dinobot. Sludge`s strength is considered to be second only to Grimlock`s in the Dinobot faction. Sludge also has the great power to shake the ground violently and make huge tremors when stomping around in his Brontosaurus mode, which is a good weapon for shaking up Decepticons. Sludge also was seen at times to shoot laser beams from his eyes and an energy weapon from his mouth. Sludge`s biggest weakness is his belief that the strongest Autobot should lead and not necessarily the smartest. Another weakness of Sludge`s is that he is depicted as being mentally slow. He joined the Autobots in the cartoon and comics in their first year, but didn`t have a toy until 1985. The other members of the Dinobots are Slag, Snarl, Swoop and their leader, Grimlock.
