Shinsei

(This story has many references to Saint Seiya, such as the armor and some knights, but you can mention any knight you want).

Now. Shinsei is the reincarnation of Typhon, the father of the monsters of Greece. He had children who were very well known in Greece, such as Cerberus, the Lernaean Hydra, the Chimera, etc. Even though Typhon has reincarnated in the body of a human who seemed normal (Like Athena and Poseidon). Over the course of a few years, he was able to regain some of his abilities, such as superhuman physical strength, and creating hurricanes along with storms. Furthermore, Shinsei would take it upon themselves to acquire some colossal mythological monsters to use to their advantage in order to gain more power. Now, in hidden places like mysterious lakes or caves, Shinsei would be in charge of collecting new members.
