Shredders are large plant-like creatures that live in Torvus Bog. Upon being disturbed, the Shredder will uproot itself from the mud, then, using its helicopter-like vines, fly towards its would-be aggressor before exploding and shooting thorns at him, her or it. A relative of the species is also encountered in Torvus, the Shrieker.
Metroid Prime 2: Echoes
Exploding flying plant.
Durable plantform seeks enemy targets and flies toward them, exploding on contact.
The Shredder spends most of its life in the earth. When agitated, it will spring from the ground, then begin to fly toward its foe. Should it reach its target, the Shredder will explode with considerable force, releasing a cloud of thorns as it does. Shredders are resilient, but can be eliminated with concentrated weapons fire.
