Jorgandr

Jorgandr is a gigantic worm-like monster and a boss from Final Fantasy Legend III which faced the heroes of the story after it summoned a large sandstorm that engulfed the mystic-vessel Talon and subsequently caused it to crash: the monstrous Jorgandr proceeded to instantly attack the heroes on the ground but was defeated, however thanks to the monster's actions Talon was destroyed. Jorgandr is based on the snake-god Jörmungandr from Norse mythology.
