Ultraman Leo (character)

Ultraman Leo comes from Planet L-77(Leo planet), and takes the human form of Gen Otori. Ultraseven appears to fight a new foe, Maguma-sejin and his two "pets", the Red and Black Gillas. However, Magma badly wounds Seven, graphically breaking Seven's leg. Ultraman Leo drives off the foes, but Ultra Seven is confined to his human form because of his injury. The Ultra Eye is destroyed when Dan attempts to transform, and Dan takes up a role as the captain of Monster Attacking Crew. Gen is a gymnastics teacher on the side. Gen and Dan regularly train together, allowing Ultraman Leo to learn many moves in human form. Mid-series, MAC is destroyed by Commander Black, and Dan vanishes, seemingly abandoning MAC. Gen spends most of his time later training the kids to defend themselves. When Commander Black captures Gen when he cannot transform, the kids kill Black in rage. Satisfied that the kids are able to defend themselves, Gen sails out to sea, his favorite student watching as he leaves.

Ultraman Mebius
Ultraman Leo returns in Ultraman Mebius to help Ultraman Mebius fight Alien Reflect, an alien that defeated Mebius and stated that he would return later to kill Mebius.

Gen is displeased with Mebius performance in the fight with Alien Reflect and refuses to accept him as the defender of Earth. Gen then challenges Mirai to a one-on-one combat (as Ultraman Leo and Ultraman Mebius respectively) which leads to Ultraman Mebius' defeated at the superior combat skills of Leo and the power of the Leo Kick. Mirai then accepts the martial arts robes that Gen offers him and begins to train and practice to develop new techniques and develops his own version of the Leo Kick. It is called mebium drill kick. When the monster returned, Mebius' training was paying off until the monster captured the ship containing his GUYS comrades. The monster told Mebius to surrender or GUYS would be killed. Before Mebius can do anything, Gen who had been observing the battle nearby triggers his transformation into Ultraman Leo and together with Mebius, GUYS was saved and the alien destroyed by the combined power of Mebius new kick attack and the Leo Kick. Ultraman Leo then accepts Mebius as Earth's defender and departs. Reference Episode 34 of Ultraman Mebius.

Ultraman Leo is also seen with his twin brother, Ultraman Astra, along the other Ultra Brothers to resurrect the Sun during the final episode of Ultraman Mebius.
