Jack the Ripper

Jack the Ripper was a murderer who operated in 1800's London, who killed over 300,000 prostitutes. Almost nothing was known about Jack the Ripper by anyone until the Moon Wars, where on a trip to London, Shota Trump uncovered his personal 150,000 page diary, where much would be learned about him by his chronicles of his murders once it was translated. However, Jack the Ripper spoke in a completely unknown and so far impossible to translate language, which was passed on to his great grandchild, Zodiac.

Family
It is completely unknown how Jack had a family, and there are no records, and he was known to murder any woman he could find. Rumors say that he had a baby with a transgender man, agreeing to pay for the surgery after the baby was born.

Spring-Heeled Jack
At one point, Jack the Ripper met a prospective serial killer named Spring-Heeled Jack, who wielded a crude flamethrower and wore a mask that caused anyone who saw it go go insane or die. Jack the Ripper was not effected by the mask and casually overpowered and killed him, thinking of him as a poor imitation of himself.
