The Indomitable CPU is a treasure in Pikmin 2; it is actually a triode (vacuum tube), with the text: preceding person system.
The treasure is dropped by the Gatling Groink on sublevel 7 of the Subterranean Complex in the Valley of Repose upon its defeat. There are two of these enemies on that level, so determine which is the carrier of the treasure using the Treasure Gauge before attacking that one from behind, preferably with Purple Pikmin. It is recommended that you clear the area of Bomb rocks before venturing out with Pikmin, as they can be easily set off in the fight.
