Earth Elementor's Core, is a red, Elementor Core that most of the Elementors have, including Earth Elementor. His core doesn't seem to have anything special, it is just a normal core. In Elements of Surprise Part One, him, Water Elementor, and Fire Elementor released some type of red laser from their cores and then the laser went to Air Elementor's Core, and at that time, he has the Stasis Inhibitor on the core, which later made them merged into a four Ultralinks in one Elementor monster called Ultimate Elementor. But what is different from the others is that his core is close to his mouth. The core first appeared in the episode, Come Together Part Two.
