Return to the North!
Super Weapon R-1
A monumentally deadly snowstorm engulfs the Earth. The Ultra Garrison headquarters is frozen after a mysterious monster drills underground and breaches the walls of the base. Meanwhile, Dan Moroboshi is stranded in increasingly freezing temperatures. He loses his Ultra Eye in the blizzard and is attacked by the giant alien monster, Gandar. Unable to transform into Ultraseven, he sends one of his monster helpers to do battle. Meanwhile, Commander Kiriyama and the Ultra Force try to restore power to the base. During the monster battle, Moroboshi finds the Ultra Eye, but with a depleted solar power, he can't fight the monster. Ultraseven must then fly into the sun to replenish his energy leaving Miclas and the Ultra Hawks to fight Gandar alone.
