Sonic emitter

An invention of Blackarachnia's, the sonic emitter is capable of blowing a sizable hole in, say, the bottom of a Maximal exploration vessel.

Fiction

Beast Wars cartoon

Blackarachnia, Waspinator and Terrorsaur were sent to dig a tunnel under the Axalon, so they could plant the sonic emitter under it and blow a hole in its underside. Frustrated at their progress, Waspinator flew off and managed to alert the Maximals to the fact that something was up in the area. Tigatron was able to slip into the cave, shoot up the three Predacons, and grab the emitter right when they were ready to fire it off. Though he dashed for the exit, the Predacons gave pursuit, and Blackarachnia alerted him to the device's imminent explosion. Tigatron threw the sonic emitter, embedding it in the cave floor as the Predacons fled, and a short time later a huge explosion ruptured the ground not far from where the other Maximals were standing. When they investigated, they found Tigatron had survived the explosion. A Better Mousetrap
