|Seasons||Shining Miracle Pretty Cure|
There is little known about Kaos' past. What is known, is that she, when she was younger, was a normal human, but something caused her to achieve extraordinary powers, and that she created Ragnarök Republic only months after that.
Although it is unknown exactly how hold Kaos is - even if it's suspected to be a really large number - she appears to be around the same age as the cures. She is also really childish, and knows what she wants, and she wants it now. In a battle, she fares surprisingly well, and does several times engage hand-to-hand combat against the cures, without ever getting overpowered. She does also have an aura around her that makes her feel a bit off.
Kaos is seen, during the very last episodes of the series change into a Cure-like form, which seems to be based on all the opposite things Cures represent. In this form, she is able to summon, and control, even more Saiarks than in her normal form. She has powerful mind powers, everything from mind control, to telekinesis. She is also able to take control over other's attacks using the telekinesis, as long as they are not too powerful. On top of this, she can create pure black energy waves, and teleport.
Kaos (カオス): Kaos in Swedish means Chaos.
