Freakish, semi-aquatic hybrids of surly radioactive reptiles and insectoid slave-laborers from deepest space, godzilunans roam the wastelands with but one purpose:  destruction.

And rampant destruction, at that.

Godzilunans stand 30' tall, and their bodies are covered with thick scales and chitinous segments that make them nigh-impervious to *all* armaments  (meaning they suffer only one-third damage, no matter the weapon type).  Their bulbous, distended crania throb with menace.

A godzilunan can exhale a blast of pure radiation every three rounds that does 12d6 damage.

After a particularly satisfying rampage, godzilunans bury themselves underground or inside icebergs, going dormant for months or years at a time.  They inevitably awaken at the most inopportune times for local settlements.
