In Leo: I Am the Second-Generation Lionheart Emperor

Long Fei was reborn on Planet L77 as the eldest son of Emperor Arus of the Lionheart.

From the start, he had nothing. He had a System, but no ability to transform, so all he could do was train under Doryu alongside Leo and Astra.

It was only after the Magma aliens invaded the Land of Light as their vanguard, and Arus returned injured from transforming to fight them, that Astra was captured.

That was when Long Fei finally saw the transformation device that belonged to him: the Heavenly Dragon's Eye.

Later, when Leo went to Earth, Long Fei followed him. With Long Fei backing him up, Gen Ohtori finally stood tall. Dan Moroboshi went from being the Alien-with-a-Cane to the Alien-in-a-Wheelchair, and eventually upgraded to the full-fledged Alien-on-a-Stretcher!

Arus always wanted the protagonist to inherit Planet L77, but the protagonist refused at every turn. When a System mission tasked him with expanding L77's fighting force, he went straight to the Land of Light to poach its talent.

Staring at the empty Space Garrison, Takeru fell into deep thought!

Takeru: Did I seriously just become a commander with no troops?

Long Fei: Right, you got it. Just between us, there are still plenty of Ultraman from the M78 Nebula lining up to join L77. So, should I say yes? Or should I say yes?

Arus: My son Ares (Long Fei) has the makings of an emperor!

Doryu: Ares is the worst student I've ever taught!

Seven: You bastard, Ares! Gen wouldn't dare talk back if you weren't around. Ever since you came to Earth, I haven't had a single day without an injury! Damn it!

Belial: I was supposed to hate Ken. Then, while I was unconscious, Ares jabbed my head with a syringe as thick as an arm and nearly punched right through my skull. Now it's either him or me.
