Female Mewtwo
This Mewtwo is a female who was “created” (Experimented on as a Baby Mew) by Team Plasma. She is related to the Mewtwo of the Kanto Region, and is his twin sister.
She is far calmer than him, and not as wary about humans, as she doesn’t have misanthropic views like her brother. She also has an extremely close bond with a group of Genesect that were also experimented on by Team Plasma. Mewtwo has the ability to Mega Evolve into Mega Mewtwo Y during battle.
…She is the mother of Baby Mewtwo.
