Mighty Base (マイティベース Maiti Bēsu) is the headquarters of Ultimate Force Zero in another dimension. It first appeared in Ultra Zero Fight. It is based on the Inter Galactic Defense Force Headquarters in the Land of Light. Not much else is known about it.
During the climax of the battle between Zero Darkness and Ultimate Force Zero, Zero (under Belial's control) fired a Deathcium Shot that cut straight through Jean-Bot and destroyed Mighty Base. In the finale, Zero used the Shining Star Drive to save his teammates and fix Mighty Base.
