The Treaty of Versailles which the Philippine Republic leader Windsor didn't attend was signed by the allies and axis on June 19, 1919.
This then officially ended the first world war that the world created.
Exactly on January 19, 1921, the Philippine Republic's secret scientist has finally finished the first super human serum that makes the taker of the serum faster than a normal human, stronger physically and mentally, does not age the user, and makes the user smarter, immune to any diseases, virus, and poison, and faster healing capabilities compared to a normal human.
Of course, the serum got injected into Windsor making him the first human superhero. After the success of the experiment, the evidence of the formula was all burnt to ashes. Though Windsor commands the scientist to make different serum weaker than the serum that he took and inject it into the one who is willing and has the potential to be a good soldier of Windsor.
Soon the private and secret agents that protect Windsor and go out to deep enemy territories to spy were created. They were called "EYES" meaning they were the eyes of Windsor.
After the creation of the EYES other secret services were created to protect, spy, counter-terrorism, and many more.
