She is the main villain of Dragon Ball Online and features in the Super Dragon Ball Heroes promotional anime and manga. This Xenoverse character is Dabura's sister. Redemption does not seem in the cards for Towa, who is pure evil. We have, of course, had some female baddies in the long life that Dragon Ball has seen, but many are either in minion roles like Mai or were quickly turned into complex characters or redeemed, such as Android 21.
Towa is an oddity in Akira Toriyama's work.
