Daiki Saikyo, The Ultimate Human (RP book)

For generations the the Saikyos have been considered a family and clan of battle bred humans with Olympic level skills, much like the Kure clan or the Zoldycks. Most of the old generation family clan members who have the Saikyo blood in their veins have died out or have been killed, due to the existence of competing with powerful alien races like Saiyans, Arcosians and Kryptonians, people who became mutant thanks to the X gene, the introduction of quirks, a variant of the mutation, along with Magic, Haki, Semblances, Nen, etc. But one son of the fearsome Daiken Saikyo a man otherwise known as Echelon, rose above and had a son. His son then became the Outlasting Hero, known as Apex who eventually grew and defeated the most vile of monsters and god like beings that could warp reality. This is a book about him.
