Leonix is the genetic successor of the Thunderbloods. The legendary ultimate life form once ruled many original universes. After its power and spiritual body were dispersed, it was inherited by different types of individuals. These successors are called "Leonix".
They have the ability to control monsters, but they will fight each other because of the fighting instinct in their genes. The final winner may become a new generation of Thunderbloods.
Howley, a Leonix on Earth, accidentally awakens and becomes Leonix. He is not the only one here, there are also local monsters, space monsters, and space people. In addition to these, Ultraman will appear once the monsters invade cities and villages.
Opportunity or luck may have allowed him to continue walking in the universe
