Bomb from FFXI
The Bomb and its counterparts' names are related to similar real-world explosive or explosive-esque items. Their trademark skill is a self-destruct attack; after the Final Fantasy series moved to a 3D engine, the Bomb picked up a new habit of growing and becoming more powerful each time it is attacked until finally exploding.
In Final Fantasy IV, Bomb was a secret summon for Rydia. There also exists a dummied sprite nicknamed K. Higuchi after one of the game's battle programmers, Katsuhisa Higuchi, identical in appearance to the regular Bomb seen in the hidden Developers Room as an Easter Egg. In Final Fantasy IV, the Mom Bomb (in the English version) is a boss that consists of several bombs fused together. In Final Fantasy V, the boss Byurobolos is a Bomb variation with teamwork traits. In Final Fantasy X, a special monster called Bomb King could be created through the Monster Arena. In Final Fantasy XII, the Bomb King also returns as a boss, and a bomb is used as an icon for the berserk status. In this installment of the Final Fantasy series, Bombs introduce a new devastating self-destructs called, "Chain-Reaction" where one bomb can make all the surrounding bombs self-destruct also. The first time the origin of the Bomb is given is also in FFXII, where it is described as a creature created specifically to fight wizards. Bomb has appeared in all Final Fantasy installments except for the first one, as well as in Chocobo's Dungeon 2, Chocobo Land: A Game of Dice, Final Fantasy Fables: Chocobo Tales, and Itadaki Street Portable. It was also an obstacle in Mario Hoops 3-on-3, and was featured as a Gummi Ship model in Kingdom Hearts. Alternative names include Balloon, Purobolos, Grenade, Mine, Pineapple, etc.
