This weapon launches a plasmatic Ion Bomb, which will either explode within approximately ten seconds or be detonated remotely at will. Like the Disintegrator, it disintegrates a human's body, leaving no corpse.
This is changed in Path of the Furon where all weapons can produce DNA from destroyed humans. Also the Ion Detonator can stick to objects and even people, it also is the only weapon that can be functioned in the Temporal Fist state. It's upgrades allow it carry more ammo or produce a stronger blast. In Big Willy Unleashed, it's given a different look, but its basic function is the same.
