A Gadora(ガドラーGadorā) is a Bio-Barrier living on Zebes, but X Parasite mimics are also present on the BSL. They are easily recognizable by their single large eye that composes most of their bodies and are always found blocking entrances to nearby boss rooms. Their skin is seemingly covered with hardened scales and spikes. Samus can destroy them by firing three Missiles or one Super Missile at the creatures' soft, ocular organ when their eyelids open. They will sometimes defend themselves by covering their eye with a strong shield which they immediately launch as a wave of plasma; in other appearances, they shoot three consecutive spheres of plasma which home in on their target.
