During the battle at Jupiter, the Z-Master was further enhanced by utilizing The Power, which it absorbed from Jupiter directly through Hair Primeval. This ultimately proved to be a weakness as well as a strength, when Star GaoGaiGar, King J-Der, GenRyuJin, GouRyuJin, Mic Sounders the 13th and Big Volfogg entered the Z-Master's body through the same channel. Within the interior, they penetrated all of the way to the Heart, where King J-Der sacrificed himself to destroy the Z-Master by overloading Heart with The Power, which caused the entire Z-Master to swell and ultimately explode. This halted all Mechanization and destroyed all Zonder Metal, with the exception of the New Machine Species that dwelt deep within Mikoto Utsugi.
