CPU (Final Fantasy IV 2D)

The CPU, also known as the ControlSys, is a boss from Final Fantasy IV. It is the game's penultimate boss, excluding the various optional bosses in the Lunar Subterrane. The controlling unit of the Giant of Babil, CPU directs the giant's actions. Cecil and company realize CPU is the giant's only weak point, and fly the Enterprise inside in an attempt to stop the war machine. The CPU is protected by the Defense Node and Attack Node.

Strategy
The CPU has high HP, but it is an easy fight. At the start the player should have everyone attack the Defender until it is out; CPU will cast Reflect so most magic will bounce back. If the player takes out the Attacker, CPU will use Globe199 (which deals 9999 damage to a single target) twice, killing two party members, so the player should let the Attacker attack the party, and have Rosa cast Curaga on all party members while the others attack CPU. Eventually CPU will lose all its health and the player can finish off the Attacker. In the SNES version CPU uses Globe199 to counter a physical attack, so the fight becomes easy if FuSoYa uses Meteo and Rydia uses Quake (or Bahamut if she allready knows it). Using this method the battle would last only a few turns, as long as 1 Ether2 is used on FuSoYa.

Nintendo DS
The player should finish off the Attacker immediately, as it has low HP, but extremely high Attack power. The player should defeat the CPU next, because destroying both Nodes causes the CPU to use Globe199, and the CPU has no attacks whatsoever without its Attack Node. Any summon except Titan can be used to damage the Attack Node and CPU simultaneously, while leaving the Defense Node untouched, to prevent Globe199 from triggering. The Defense Node is equally helpless after that.
