Ultimate One

Also known as The Ultimate Ones or Types.

Eight lifeforms (not including Type Moon; apparently the inhabitants during this era were unaware of its existence) from other heavenly bodies. Beings that don't mix well with the (common sense) rules of this planet; no mind, no concepts comparable with "death", hence "destroyed" ones haven't truly "died". Will continue to operate until objective is complete.

True identity are the ultimate beings from each of the other planets. Each has the power to single-handedly exterminate the existing lifeforms on this world. Called Aristotles by humans, but these beings do not even have the concept of names. Aristotles do not contend against each other and operate freely of each other.

Among them, there are those who learn the concept of "knowledge" from the lifeforms of this planet. Further, several Aristotles have made contact with humanity. Following the destruction of Type Saturn, the relay unit for the orders of each of the planets, the Ultimate Ones would move on into the final battle.

Confirmed physical "destruction" of 3 by humanity: Venus, Pluto, Jupiter. Saturn is later destroyed meaning that there should be two more on the surface and two remaining in the blood sky. Uranus and Neptune are described as destroying the majority of the Type Venus monitoring base which would mean that these are the ones that are probably still on the surface. Which would mean that the remaining ones in the blood sky are Mercury and Mars? It's also possible that Neptune and Uranus were able to breach the cloud barrier after the destruction of Saturn.
