Deathgaze (Final Fantasy VI)

Deathgaze, also known as Doom Gaze, is a boss in Final Fantasy VI. It is difficult to find, as it hides in a random location on the World Map of the World of Ruin, and can only be fought by contacting it with the Falcon. Its first move is to cast L.5 Death on the party, effectively weakening it. There is no time to heal from this, as Deathgaze is prone to escape at any time (usually after two turns). Casting Fira, Firaga, and Holy spells work very well against it, as does Gau's Io Rage, which has Flare Star, which will always deal 9,999 HP damage to it. It attacks using Death, Aero, and Blizzaga. Another useful strategy is to use Fire Rods or Pearl Rods on Deathgaze since these will ignore his high defenses and Auto-Shell. After several turns, it escapes from battle, forcing the player to find it again. However, it does not recover any HP, and starts off the next battle with however much was left. It drops the Bahamut Magicite when defeated.

If you use the Vanish/X-Zone bug to defeat Deathgaze, you will not receive Bahamut (although the Vanish-Doom bug will work).
