オトナシクコウサンスルノダ！！ Gerrrr... I came to this planet from a flying saucer.
Gelm13 is a cyan alien with an amorphous, drippy body composed of goo. It can morph and expand its body freely, namely into other Pop'n Music characters like The King, Nyami and Rie-chan. In his Win and FEVER! Win animations, Gelm13 is seen turning into a woman turned back from the screen.
Cyber makes an appearance on Gelm13's Miss animation.
