Act 52 Stars 10
Very little is known about this powerful being. The threat of Sailor Chaos came into existence as a result of Sailor Moon's decision not to destroy Chaos when it merged with the Galaxy Cauldron, allowing it to achieve a Senshi form. According to Sailor Cosmos, Sailor Chaos would appear in the distant future, and become the greatest adversary the Sailor Soldiers should ever encounter. The war against Sailor Chaos caused destruction on such a scale that future would be irreparably damaged. For this reason alone, Sailor Cosmos fled to the past, in order to persuade Sailor Moon to destroy Chaos before it became a Senshi, thereby changing the future but also killing every living thing in the galaxy by destroying the Galaxy Cordon, including herself.
Sailor Cosmos would eventually return to the future, having changed her mind about changing the past in order to continue her war against Chaos, though the result is never revealed. However, this also means when Sailor Cosmos fled, remnants or Sailor Chaos itself still remained in the far future to continue to wreck havoc in Cosmos's abscense.
- Observing closely, fans notice that Sailor Chaos bears a resemblance to Sailor Galaxia in appearance only because a headdress, but upon closer inspection it is not the same headress and Galaxia is not the only one to wear a headdress or have long/semi-long hair. Also, Sailor Galaxia are completely different beings. It is also known that Galaxia is NOT reborn as Sailor Chaos but that the being Chaos itself, is reborn as Sailor Chaos.
- Sailor Chaos has live snakes, from the looks of it, attatched to her fuku.
- Chaos has two previous known incarnations. One in the past and one in the future. Metallia is Chaos's first known incarnation. After her death by the hands of Sailor Moon in the first arc, we find out in the second arc she was reborn as Wiseman in Crystal Tokyo who was also later killed by Sailor Moon after his skeleton merged with the planet Nemesis. Pharoah 90 and Nehelannia may have been influenced by the evil of Chaos in the manga but were not directly linked with Chaos, as Nehelannia was from a far distant place outside the Solar System and Pharoah 90 was from another dimension entirely.
- Chaos is the only known character in the manga that has been known to be born both male and female. In the anime, this characteristic is given only to the Starlights.
