The Chimera Brain is an enemy from Final Fantasy X encountered in the northwestern area of the Calm Lands. It uses several magic attacks in battle: a standard Lightning-based attack on par with Thundara, a Fire-based attack called Megiddo Flame, and Aqua Breath, which Kimahri can learn as a Ronso Rage skill. In addition to magic, it also has a powerful physical attack. If it gets bribed successfully it will drop two Level 4 key spheres, a very rare item in the game. Chimera Brain will drop weapons with Magic +5% or +10% or armor with Magic Defense +10%.
