The Trigger of Distruction is difficult, since it's supposedly able to destroy the entire universe. Since no other capabilities were shown in the anime (that I know of) it would make sense that it would basically be a large, heavily armored mecha with a single one-shot attack that destroys the universe (with a large charge up time of course). And I would guess that that kind of attack would pretty much end any El-Hazard game I don't remember if it needed Kalia to fire it or not... been too long since I've seen El-Hazard 2.
