Stress fracture cannon

Superion's specialty is breaking things. And few weapons are as well-suited to breaking things as the stress fracture cannon. Its beam finds and overloads a target's natural fracture points, shattering it. The weapon can be set to varying levels of precision—it can crack an eggshell or cause a seismic disturbance. Guess which one Superion prefers.
Flintlock, one of Landfill's Nebulan partners, transforms into a stress pistol with infra-red sighting which can induce metal stress and metal fatigue in its targets, eventually causing them to fracture—though Landfill is probably still feared for his hygiene more than anything else.
Fiction
Marvel The Transformers comics

While watching a vision of the future of the Transformers involving a clash between the Special Teams at the Pullen Power Plant, Optimus Prime and Buster Witwicky observed Superion using his stress fracture cannon to collapse the ground beneath the retreating Menasor. Second Generation!
A point-blank shot from Superion's stress fracture cannon caused a malfunction in Devastator's coupling links, forcing him to de-combine. ...All Fall Down!
Notes
- Somehow, when Silverbolt wields Superion's stress fracture cannon, it becomes an electrostatic discharger rifle. Neat trick.
