In Final Fantasy VII, Bahamut is also accompanied by three more powerful versions: Neo Bahamut (Giga Flare), Bahamut ZERO (Tera Flare) and, in Final Fantasy VII: Advent Children, Bahamut SIN. The attacks are named for the SI prefixes for ten to the powers six, nine, and twelve; the third is commonly misread as "Terra Flare" or "Tetra Flare". Also worth noting are that the suffixes and prefix for the variations of Bahamut in Final Fantasy VII and Advent Children are taken from the names of old Japanese fighter planes: KAI Bahamut ("Neo Bahamut"), Bahamut REISHIKI ("Bahamut Zero"), and Bahamut SHIN ("Bahamut TREMOR").
