About
Ultraman Hikari invented a medicine to turn Ultramen into human size, but he accidentally splashed it on Astra and Leo, and they were unfortunately teleported to Earth. Characteristics of Ultramen: Silver Tribe: Skin is silver and smooth. They have crests instead of hair. Oval yellow eyes. Generally silver bodies. They have a blue glowing Color Timer on their chest. Weak to cold. Red Tribe: Because they possess the Heart of the Sun, they are even weaker to cold than the Silver Tribe. Most Red Tribe members have a diamond-shaped lamp on their heads. Generally red bodies. History of the Leo Brothers: They lived on a planet called L77 in the Leo constellation. The prince Leo and his brother Astra lived in peace. However, the planet was invaded and destroyed by Alien Babarue. They were later rescued and protected by the Land of Light in the M78 Nebula. Both brothers belong to the Red Tribe.
