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 would ever encounter. She confessed that, in her time, their forces were far from capable of resisting her might. The war against Sailor Chaos caused destruction on such a scale that future landscape would be irreparably damaged. For this reason alone, Sailor Cosmos fled to the past, inorder to persuade Sailor Moon to destroy Chaos before it became a Senshi, thereby changing the future.
Sailor Cosmos would eventually return to the future, and continue her war against Chaos, though the result is never revealed.
- Observing closely, one can notice that Sailor Chaos bears a resemblance to Sailor Galaxia in appearance. The headdress, which is one of Sailor Galaxia's unique Sailor fuku features, can also be seen as a part of Sailor Chaos fuku.
