Nyerk

The Nyerk is a biological weapon developed and deployed by the GEATHJERK Federation Supreme Armada. Designed to be unaffected by conventional weapons, the Nyerk is a gelatinous amoeba with the ability to form its body in whatever shape it so desires; in fact, its primary attack is the morphing of its body into stretched tendrils, which are then used to strike the enemy causing immobilization. Due to the fact that conventional weapons cannot harm the Nyerk, the best strategy to defeat it is to use Wonder Blue's United Sword to cut through the gelatinous outer layers, damaging its core directly.
