Gigas Worm, also known as CREEP in the Nintendo Entertainment System version, is an enemy in the original Final Fantasy. It is weak to Fire, so casting Fire is the easy way to defeat this enemy. Gigas Worms appear early in the game, and they should not pose a threat if the player has spent some time leveling his/her party up. They appear in the Chaos Shrine, in the present, and outside towns such as Pravoka and Elfheim.
