Chaos (Final Fantasy boss)

Chaos is the final boss of the original Final Fantasy.

Strategy
Chaos is the toughest enemy in the game in the Nintendo Entertainment System/PlayStation versions, and one of the toughest enemies in the Game Boy Advance/PlayStation Portable versions. He has a plethora of powerful and debilitating spells at his disposal. The most commonly used spells are Firaga, Thundaga, and Blizzaga, however, these are his weakest spells. Chaos' stronger spells are Blaze, a strong Fire-element attack, Tornado, a strong Wind-element attack, Tsunami, a strong Water-element attack, and the instant-kill Quake, all of which are attacks used by the Four Fiends. Rarely, Chaos will conjure Flare, his strongest spell. In terms of status effects, Chaos has Slowra, which can decrease the hit rate of one character, and Haste, which increases his hit rate.

It is wise to give three of your characters a ribbon. In the Nintendo Entertainment System/PlayStation versions, there are only three ribbons, so one of your characters will have to make do without a ribbon. It is recommended that you give the ribbons to your mages. In the Game Boy Advance and PlayStation Portable ports, you can get a fourth ribbon, so you can give ribbons to all of your characters. The ribbons will decrease the power of all of Chaos' spells, except for Flare. Protect Rings are also recommended, as they will protect your characters from Earthquake. Slowra can be countered with Haste.

Cast Haste on all your physical attackers. Temper doesn't work in the Nintendo Entertainment System version, but if you're playing any other version, cast it. Chaos is highly resistant against magical attacks, so opt for weapon strikes. Have your physical attackers use the Giant's Glove, then attack. Have your White Wizard or Red Wizard heal every turn, and have your Black Wizard cast Temper on everyone. If you're playing the Nintendo Entertainment System version, then have your Black Wizard aid in the healing with a Heal Staff or a Heal Helm.
