Ultraman Dyna (ウルトラマンダイナ Urutoraman Daina?) is the protagonist of the TV Series Ultraman Dyna. Ultraman Dyna is a very skilled Ultra, as he is the successor of Ultraman Tiga, the ancient Warrior of Light, bearing abilities similar to him. His human host is Asuka Shin, a very funny, sporty, somewhat shy yet serious in proper situations guy. Asuka is a member of the Super GUTS squad, a group of heroes that defend Earth from invaders from space. In the finale of the series, Ultraman Dyna was believed to be dead, but he was without knowledge teleported by a worm hole to a gap between dimensions.
