Hellfire Chasm

Hellfire Chasm is a bonus dungeon which appears in remakes of Final Fantasy starting with the Game Boy Advance version. It does not return in the Final Fantasy Pixel Remaster release. It is a massive, lava-filled dungeon located on the Cardian Islands, and is one of the Souls of Chaos. The bosses of Hellfire Chasm are the Archfiends from Final Fantasy IV—Scarmiglione, Cagnazzo, Barbariccia, and Rubicante—each fought separately.
