Giant Beasts for All, but I Can Transform into an Ultraman Monster!

A meteorite from beyond the heavens crashed into Blue Star, bringing unprecedented disaster to its people. Countless plants and animals evolved into primordial giant beasts under the radiation of the meteorite's energy, leaping to the top of Blue Star's food chain! After years of research, humanity developed giant-beast gene serums. By injecting a serum and fusing with giant-beast genes, people could transform into giant-beast warriors, fight the primordial beasts for Blue Star's resources, and preserve human civilization. Meng Chen was so talented that he offended the children of the powerful. They snatched the gold-grade serum that should have been his, leaving him with the inferior silver-grade one. His resentment reached its peak, awakening the Ultraman Monster System. As long as he had enough gene points, he could transform into any monster from the Ultraman universe! Hyper Zetton, Etelgar, the Alien Empera, Lugiel, Yapool, Greeza, Gatanothor, Grimd, Dark Lugiel, Dark Zagi, and even Ultimate Life Forms were all within reach! Meng Chen: “Blue Star is only the beginning. My goal is the stars and the sea, and the Myriad Worlds!” ~ P.S. The blurb doesn't do it justice, so please read the story.
