Chibiusa Tsukino (Parallel Universe)

Chibiusa Tsukino, better known as Dark Chibiusa is the titular main protagonist villainess of Dark Chibiusa: A Sailor Moon Story. Like her main counterpart, she is the princess of the 30th Century Earth and the daughter of Neo-Queen Serenity (Usagi Tsukino/Sailor Moon's future self) and King Endymion (Mamoru Chiba/Tuxedo Mask's future self). Dark Chibiusa is the twisted alternate version of the heroic main-universe Chibiusa Tsukino/Sailor Chibi Moon.

While a tragic character, as time passes, the fallen princess becomes more and more brutal and delusional, eventually becoming a spoiled, power-crazed tyrant with a god complex bend on ridding the universe of all evils by any means necessary and ruling it as a goddess.
