Aurora Buckly used to live in the futuree of a girl named Sally, who happened to be Rini's best friend. The Wiseman, desparate to defeat the Sailor Scouts in the present, came up with a new scheme to fight the Sailor Scouts with a Sailor Scout. His forces captured Aurora one day, brainwashing her onto their side. A short time earlier, his forces had also recovered the infamous Star Crystal from the remains of Queen Beryl's old palace. They fused the power of the Star Crystal to Aurora, renaming it the Dark Stone. Now Sailor Nega, Aurora was transported back in time to Rubius, her main mission to find the identities of all the Sailor Scouts. To make her seem as normal as possible, she attends Crossroads Junior High as well as having an apartment in the sky-rise apartment complex of Sandy Village. |
| "Nega, Dark Stone, Power!!" | |
| This is Sailor Nega's transformation command. Beams of dark light come out of the Dark Stone and encircle her while she transforms. |
|
| "Nega, Dark Stone, Drain!!" | |
| Sailor Nega shouts this to drain anyone of his or her energy, which is stored in the Dark Stone. She needs this energy in order to monsterize humans. |
|
| "Nega, Dark Stone, Monsterize!!" | |
| Sailor Nega cries this to transform humans into slaves of the Negamoon. They become hideous monsters who do whatever Sailor Nega commands them of. She can even use this command to turn the Sailor Scouts into nega-slaves, but only when they're not transformed, because their scout form protects them from her power. |
|
| "Nega, Dark Stone, Transport!!" | |
| Although most henchmen and generals of the Negaverse and Negamoon can just disappear without a command, Sailor Nega somehow is unable to. She harnesses dark energy from her Dark Stone and transports herself to a new location. |
|
| "Nega, Dark Stone, Hypnotize!!" | |
| Sailor Nega unleashes dark energy from her Dark Stone into the eyes of her vicitm, persuading the human to do her bidding without the need to transform him or her into a monster. However, this ability requires a great amount of Sailor Nega's own energy, which is why she uses it rarely. |
|
| Dark Stone | |
| Formerly the Star Crystal, which Zoicite had used to extract the Rainbow Crystals, the Dark Stone is the source of Sailor Nega's power as well as receptacle for the energy she collects. Found shattered in the remains of Queen Beryl's palace in the future, the Wiseman repaired it and renamed it the Dark Stone, fusing its power to Sailor Nega. | |
