Combaticon leader Onslaught wields a sonic stun-gun, a weapon capable of "stunning" a hillside into powder. When he combines with his teammates into Bruticus, the fearsome combiner carries the weapon as well. Terrorcon leader Hun-Gurrr also carries a sonic stun-gun, which is also wielded by Abominus.
Decepticons have a funny concept of "stun".
