Self-Destruct

Self-Destruct, also known as Exploder, Kamikaze, or Blowup, occurs most commonly as a Blue Magic spell. It typically KOs the spell caster while doing large damage (sometimes fire-elemental) to enemies. It is commonly used by Bombs and their ilk. Enemies that Self-Destruct usually result in no Experience Points, gil, or item drops being awarded for defeating that enemy.

Final Fantasy II
Like most Final Fantasy games, the Bombs and their ilk use this attack to deal massive non-elemental damage to one player, and in turn KOing itself. It is never used when the enemy is at full HP, and does damage equal to 20-40 minus the target's Defense x the level of the ability. For instance, if a Balloon uses Self-Destruct 1, a character with 40 Defense would completely negate the damage done from its attack.

Final Fantasy III
Bomb-type enemies use Self-Destruct whenever they are not at max HP, and will deal damage to one party member equal to 4x their HP when they use the ability.

Final Fantasy IV
Bomb-type enemies, Armored Fiends, and Barnabas use Self-Destruct when low on health or in response to magic. Rydia can also learn the Bomb summon, which does damage to an enemy based on her HP.

Final Fantasy V
Self-Destruct is a Blue Magic spell learned from Azulmagia, Motor Trap, Bomb, Purobolos, Grenade, Gilgamesh or from Prototype or Unknown #171 by controlling either with a Beastmaster. The attack inflicts KO on the user to inflict non-elemental piercing damage to one target equal to the user's current HP. It costs 1 MP to cast.

Final Fantasy VII
Bomb Blast is Bombs and Grenades' suicide attack in Final Fantasy VII. It deals heavy damage on one target. Self-Destruct is another suicide attack a lot like Bomb Blast used by 2-Faced, that will either use Self-Destruct or Cure 3 on a party member as its final move before dying.

Final Fantasy VIII
The Kamikaze command can be junctioned to a party member. It is initially learned by the Cactuar GF, but can be taught to any GF by using the Bomb Spirit item. Kamikaze is one of the most powerful attacks in the game, with the ability to reach 60,000 points of damage at the cost of losing the character. The amount of damage done is equal to the character's max HP multiplied by six, although the attack can critical. Any GF junctioned to the user that is removed from the battle due to this ability will still receive EXP and AP.

The Bomb enemy uses the Suicide attack after it has used Grow three times, and deals non-elemental damage to one party member.

Final Fantasy IX
Blowup is a spell only available to the Bomb enemy during the battle aboard the Prima Vista with Steiner. When the Bomb uses this ability, it blows up and deals damage to Steiner, automatically ending the battle. The incarnation of the Bomb fought later in the game as a regular random encounter does not have this ability.

Final Fantasy X
Kimahri can learn Self-Destruct as a Ronso Rage Overdrive from Bomb, Grenade, Puroboros and Biran Ronso. When used, Kimahri is removed from the battlefield and cannot be revived or replaced. It inflicts damage on one enemy equal to three times Kimahri's maximum HP.

Final Fantasy X-2
There is no ability called Self-Destruct, although similar abilities exist. Crackaboom!, Kaboom! and Kercrackaboom! are used by Bomb enemies. Hug Bug is used by Vermin enemies. These abilities KO the caster and no Experience Points, gil, and items are awarded after defeating that enemy.

The Dark Knight Dressphere ability Charon acts in a similar fashion, sacrificing the user to inflict unblockable special damage to one target, though the user is unable to be used for the remainder of the battle. It requires 20 AP to learn.

Final Fantasy XI
Self-Destruct is a Blue Magic spell that deals heavy area of effect fire damage and gives the caster Weakened, as status effect that greatly weakens the player in all respects that is usually only applied when revived with a Raise spell. It is learned from Bombs, although they actually commit suicide when they use it.

Other variations of Bombs have access to their own versions of Self-Destruct which cannot be learned as Blue Magic spells. Clusters (actually 3 small bombs) can perform a weak Self-Destruct individually, or all Self-Destruct at once to devastating effect. Djinn can use Nocturnal Combustion, which is identical to Self-Destruct but deals Dark damage. Similarly, Snolls have access to Hypothermal Combustion, which deals ice damage.

The Two-hour ability for the Ninja job is Mijin Gakure, a powerful non-elemental Self-Destruct which, unlike the Blue Magic spell, actually kills the user.
