Sin.Drella
In Reality Z-25 31-H, Sin.Drella was the supervillain alias eventually adopted by a Combat Psyker who was instrumental to Takako Yoshida's arrest, ending her days as a Yakuza assassin.
The Psyker made contact with Taki's mind when the military squad ambushed her, knocking her out but also accidentally downloading Taki's lifetime's worth of traumatic memories in an instant. Unable to deal with them, the Psyker blamed Takako herself for what happened, and went rogue as the villainous “Sin.Drella”, becoming Taki's personal archnemesis in the latter's new life as the superhero Battle Angel.

Later, she also had an encounter with Kate Five, with Kate winning the fight. Although remaining primarily Battle Angel's nemesis, Sin.Drella also carried a grudge against Kate from then on. (PROSE: Kate Five Extended Bio)
Behind the scenes
A little over a month before publishing Battle Angel Yoshida Bio (which introduced Sin.Drella in a narrative context), James Bridger published a sketch of the character fighting Battle Angel. This remains the only known visual depiction of the character or her battles with Battle Angel.
