Fics like Ultraman Deku

Once, long ago, the Earth was threatened. And then, the Giants of Light arrived. They protected this small blue planet, not just out of a sense of duty, but also out of love. It took time and effort, but thanks to the discovery of a new type of clean renewable energy on the Moon, humanity managed to persevere through their own flaws. Coupled with the discovery of a brand new gene, known as the Ultra-Quirk Gene, it allowed humans the ability for incredible technological advancements beyond their wildest dreams. Humanity took to the stars and joined the greater galactic theater, making faithful allies of many alien species they encountered, and creating the Galactic Cross Alliance. Earth and its allies established United Advancements, a special organization that deals with all manner of special situations regarding alien affairs, Kaiju events, and other mysterious happenings, without borders between its many branches. With humanity capable of protecting itself, the Giants of Light vanished as suddenly as they appeared. Until one boy makes a request. A new Giant of Light is born...
