Ultraman: Nexus from the Start, Evolving Through Combat

The young Xiao Zixing, who was living on Blue Star, transmigrates by accident to a parallel world of Ultraman and becomes a brand-new Ultra Warrior: Ultraman Nexus. From then on, Xiao Zixing takes on the mission of the Giant of Light, protecting the planet and fighting the savage creatures known as Space Beasts, as well as the darkness behind them. He gradually evolves into the universe's first light, Ultraman Noa, then begins to transmigrate to other worlds and sets off on his journey. (The story may be a little weaker at the start of the Nexus arc and could get a bit painful. After evolving into Noa later in the Nexus arc, he will travel to other worlds and begin an almost invincible life as the protagonist.)
