Ultraman Leo is the titular Ultra Hero of Ultraman Leo. Leo is an Ultra Warrior from Planet L77, which was destroyed by Alien Magma. He chased them down to Earth to get his revenge, and encountered Ultraseven, who was defeated by Magma. Leo decided to take his place as Earth's defender. Taking the identity of Gen Otori, he joins MAC, whose captain was Dan Moroboshi. After his time on Earth, Leo and his brother Astra were accepted as Ultra Brothers.

Later on, Leo and Astra became the trainers of Ultraseven's son, Ultraman Zero.

Leo was born on Planet L77 in the Leo constellation, alongside his younger twin brother Astra, with them being similar to the beings of the Land of Light in Nebula M78. His status as Prince of L77 made him heir to the planet's throne. He and Astra were talented practitioners of Space Martial Arts, with them often training with the Cosmo Beast Fighters and the amnesiac Ultraman Regulos on Planet D60 of the Draco constellation, a planet with close ties to L77.
