Triple crusher cannon
On the rare occasions when Nautilator isn't lost or slowly rusting to death, he carries a triple crusher cannon (which sounds too cool to belong to Nautilator, really) into battle.
Fiction
Marvel The Transformers comics
The triple crusher cannon generated bands of energon, which wrapped around a target and tightened until it had been crushed into scrap. Nautilator could wield this weapon in lobster mode, mount it on his mouth, convert to weapons mode and use it in a stationary position, or use it in robot mode. In weapons mode, he could also (somehow) convert the triple crusher cannon into a torpedo cannon. Nautilator's Universe profile
Animated continuity
Swindle sold Lugnut a triple crusher cannon from Talos Four for use against Blitzwing during their feud, which was used to turn Blitzwing into a very compact ball. Of course, Swindle was actually supplying weapons (and cures for their effects) to both sides of the ridiculously escalating two-bot arms race... Everything Must Go
