Lugnut is an evil Decepticon, a powerful sentient alienrobot that can transform into a purple and teal futuristic bomber jet resembling a combination of the Bartini Beriev VVA-14, the B-29 superfortress and the Heinkel He 111.
He has a big red optic sensor eye in his head and two small red sensors at each side. Lugnut also has a mouth and what appears to be a very big, prognathic jaw. His main weapon is an explosive punch attack often referred to by fans as the "Punch of Kill Everything".
In Japan his name was changed to Ragunatsu (ラグナッツ Ragunattsu) and he adds the syllable "ttsu" (ッツ) to the ends of most of his sentences.
