Subtitle: Space Sea Monster (宇宙海獣 Uchū Kaijū)


Ultraman Dyna

Reicubas was a biological weapon used by Sufume. Reicubas was released just as Dyna appeared to rescue to moving base from Sufume. After a short battle, Reicubas and Dyna emerged onto the surface of Antarctica and began a new confrontation. However, Dyna was weakened by the cold and was also distracted by Sufume's threats of crashing the Man-Made Sun onto Earth. Reicubas quickly gained the advantage and froze Dyna, causing Asuka to fall into a unconscious state from the cold and Dyna's color timer to blink. Super GUTS arrived and Reicubas immedietly began to shoot fireballs at the fighters, but was tricked by Captain Hibiki in the GUTS Eagle Beta to launch a fireball at the frozen Dyna, melting his imprisonment. Dyna then transformed into Miracle Type and fled the site, rushing towards to Man-Made Sun and launching a beam at it, reactivating the sun and freeing it of Sufume's control. Dyna became re-energized and used his Spin Slam to attack Reicubas while falling from the sky. Just as Reicubas tried to freeze Dyna again, Dyna unleashed his Revolium Wave Attack Type and sent Reicubas to an alternate dimension.
