Kirby: Planet Robobot screenshot
Esper is a floating, wizard-like enemy with a black cloak and hood. Its hood has a golden eye-like design emblazoned on it, and has a golden ball attached to the hood's tip. Underneath the hood, a white, spherical head sporting a small grin is visible. The enemy's cloak features a golden stripe. Esper's hands are white and float in midair, making them resemble the hands of Magolor.
Esper first appears in Stage 1 of Resolution Road, and appears in many stages thereafter. The enemy floats in midair, and attacks Kirby at regular intervals when he is in its range by sending forth a small, purple ball of psychic energy. In addition, Esper may sometimes project a spherical shield of energy around itself. This shield will hurt Kirby if he touches it. The enemy is also able to teleport itself short distances multiple times in rapid succession.
Esper can teleport between planes and attack Kirby from the background.
