Reggies

Regulus Ginedrive Immoral Egersis or Reggies for short is the official name of a group of people who were created and deemed failed byproducts by the Jaula Blanca Royal Scientific Research Institute.

Etymology
According to Koku, Reggies have their name derived from an ancient race of demi-humans who were prone to violence.

Background
Regulus Ginedrive Immoral Egersis or Reggies are failed byproducts created by the Jaula Blanca Research Institute from a series of experiments that were conducted over hundreds of years to revive a set of ancient winged gods. Originally known as the 'Promised Children,' these groups of individuals were normally kept locked up. However, as funds began to dwindle due to the king refusing to finance the Institute anymore, the leader of the institute came up with the idea to use the Promised Children as weapons to balance out the chaos and order of the country, leading to the creation of Market Maker.

Keith Flick surmises that this may have been what the government had originally planned and in fact may not have been interested in a successful product.

Common Traits
All Reggies are born with the ability to uses super-strength and have enhanced reflexes and skills. They also maintain an extreme innate bloodlust which normally lays dormant until it fully awakens upon the Reggie's 20th birthday. After a Reggie's 20th birthday, the Reggie will gradually start losing their mind and become more violent and mentally unstable. Most Reggies are able to keep their bloodlust in check though by using a specialized drug that regulates their testosterone and dopamine levels.

Once a Reggie has becomes completely useless, the government releases them out into the wild. The only way to kill a Reggie is by using weapons made out of blue metal.
