From the files of the Xaosologists:

They look like 35-foot amoebas with a slight geometrical form. They have two-dimensional triangular eyes, as if painted into their skin, distributed over their bodies. The slaadi claim the eyes number 13 for diverse reasons. We have yet to confirm.

Their coloration is greenish, but papery, as if ripped from a book illustration and varies when it adapts to an attack form.

CombatA Kekacauan attacks by flailing its pseudopodia at its enemies and are particularly aggressive. Although intelligent, it does not communicate by any means.Detect Weakness (Su): Any special vulnerability of a target creature can be detected, such as a red dragon’s double damage from cold. Many sages consider this to be some aspect of time travelling. Soup Ray (Su): Once every three rounds it can make a ray strike emulating its enemies’ greatest weakness, once they have detected it. This ray can be made acid, chaotic, cold, darkness, death, electricity, evil, etc., as spells, or even silver dust or ice shards through the creature’s anarch powers. The ray causes 3d8 damage to creatures without special vulnerabilities (no save), 4d8 to those with vulnerabilities (i.e. werewolf’s vulnerability to silver or positive energy to undead) and 6d8 to those that take double damage from that attack type (i.e. cold to a red dragon).Amorphous (Ex): A kekacauan in its natural form is immune to poison, sleep, paralysis, stun, and polymorph. It is not subject to critical hits and, having no clear front or back, cannot be flanked.Adaptation (Su): Every time a kekacauan is hit by a particular attack type it gains either +5 resistance against that energy type or damage reduction. For example, if it is hit by Fireball two times it gains fire resistance 10. If it is hit by weapons it gains 5/+1 damage reduction, then 15/+2 damage reduction and finally 30/+3, it cannot make itself immune any further.Habitat/SocietyThe name given to them is from the slaad tongue and is supposedly one of the thousand and one words for kinds of chaos. A pack of slaadi and a cabal of sorcerers were the first to encounter this being in combat. One of their mages tried to blast it with fireball, as he liked to. He was surprised to see the being was immune, knowing all their tactics and preferences. Later, they encountered the being again, years after, and it was surprised and almost defeated. 0EcologyOur best theory is that it travels time, thus when it had learned their fighting style, it moved backwards to fight them in the past. Its purpose is, thoroughly unknown as of yet. Some theorize they come from alternate planes or realities, but one might give those theories a skeptical look. It seems more likely that they emerged spontaneously from the chaos-matter of the plane. The only reports we got on these topics were from the slaadi that had very curious reactions. From the wave of unrelated comments, I was able to cull the assertions that it is the defensive system of the plane, one Slaad Lord or even an aspect of the Spawning Stone. We should take steps to secure our installations against these beings.
