Fighting for some time and trading blows, soon both warriors fell from the sky. While Baltan goes underground, Cosmos is wounded and out of power. At death’s door, it seemed the hero was done for until a small boy discovered him. Musashi Haruno managed to revive the hero by reflecting sunlight into the beam lamp on his head.
Revived, Cosmos took the young boy for a ride over the landscape before giving him a small gem that contained the power to summon the hero. His parting words where "One who is strong is one who is brave". During Basical’s raid on the city, Musashi tried desperately to call him but couldn’t. He was forced to watch as the alien destroyed all in his path.
Battle against Baltan
Later on, after Basical was awoken by the Sharks’ jets, Musashi found his courage and managed to call on the giant. Cosmos spoke with the Baltan guardian and demanded that he return home and depart Earth, declaring it off-limits. When he refused, the blue and silver guardian fought Basical to a standstill, until the insect-like creature morphed into his Neo Baltan form.
After being attacked by this new form, Cosmos called on the strength of his Corona mode. In this form, Ultraman Cosmos was able to thwart the invader and overpower him. Using the Prominence Ball, he dealt the final blow and put the invader down. Basical admitted defeat and shed tears before Cosmos' attack took effect. All he wanted was to give the orphaned children of his world a stable planet to live on and now that was impossible. After he fell, Cosmos used his powers to revert his body to his previous form and watched as the children of planet Baltan departed with the body of the last adult Baltan and began the journey back to their home world, beyond the solar system.
