Triple crusher cannon

The triple crusher cannon is a weapon from the Generation 1 continuity family.

On the rare occasions when Nautilator isn't lost or slowly rusting to death, he carries a triple crusher cannon into battle. This weapon (which sounds too cool to belong to Nautilator, really) generates bands of energon, which wrap around a target and tighten until it's been crushed into scrap. When combined with Nautilator in Targetmaster mode, it somehow becomes a torpedo cannon.

Fiction

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
