Fuji, Doctor

フジ博士

After his daughter Amber died, Dr. Fuji devoted his life to attempting to resurrect her through cloning. His wife was distraught and could not bear to watch his efforts, insisting that he could not bring Amber back to life. She eventually left him, yet Fuji continued working to find a way to clone Amber.
Eventually, his studies gained the attention of Giovanni, who said he would fund Fuji's project if Fuji also cloned Mew. This resulted in the creation of Mewtwo.
After the original Charmandertwo, Bulbasaurtwo, and Squirtletwo died during the experiment, Ambertwo—the cloned form of Amber—died as well, eliciting a heightened emotional response from Mewtwo. Dr. Fuji panicked and administered a form of emotion-suppressing serum to Mewtwo, which may have caused its seemingly-twisted personality. Time passed and Mewtwo matured, though shortly after gaining consciousness, it destroyed the lab on New Island, presumably killing everyone inside
