Origins
Ashtaroth is the ultimate weapon of the Aeros Empire, a hybrid of its various Gestorumque. It was dispatched to the Earth of Universe 204,091.0008932 in order to annihilate the resistance posed by Jon Hudson squad of Ferox, interdimensional warriors, and rogue Gestorumque. It kills Karkinos, Typhon, Scylla, Drakon, and Scrion; and seemingly kills Nemesis and Hyperion as well, but was ultimately torn apart by Solomon's divinely-bestowed powers.
