Monsters based off of creatures from the Cambrian era. Dire Trilobite, Hallucigenia, Nectocaris, Dinomischus, and Odontogriphus.
Dire praya dubia
Celestials that don't look pretty--old, old, old, who were beings of good before the birth of mortality. Strange creatures; interlocking and ever-spinning wheels lined with eyes, a being so beautiful reality cast a veil over it so none would see it, a creature made entirely of angles (an angle-angel, as it were), a creature composed of eyes that each behold a separate beauty of reality. Eldritch abominations--but ones that are inherently kind. Not human in the least.
More good; we are drastically, drastically low on good-aligned outsiders in comparison to evil.
The major outsider races all seem to have a CR 20 version, except for the following; Archons, Azatas, and Proteans. (technically, neither do the Demodands, but they have Titans, so...).
An Asura that can be used as a familiar, that is an actual product of divine mistake. The Tripurasura is made by other asuras, so is like a... almost-asura. The product of a product of divine mess-up. I'd like a full-fledged one, please.
More Oni! More Asura! More Qlippoth! More Kytons! I can't stress enough how much I love these.
A Rakshasa for the traitor caste, and untouchable caste.
A species of Bodhisattva. Reincarnating good outsiders, that enter the bodies of children that would be stillborn so that the parents may know the joys of raising a child. When they grow up, they remember the truth of who they are, and go out into the world to spread enlightenment. A good-aligned counterpart to the Rakshasa.
Person-spirits. Like Kami, but that follow a single person; many religions think that people have individual spirits that follow, protect, and give luck to someone, or that watch over a single household.
PSYCHOPOMPS!!! We already have a Shinigami, a Valkyrie, and one or two others... if you went into this and did more of them, that would be wonderful! Pharasma's personal force? Devoted protectors of the River of Souls, and sworn enemies of the Daemons? Or maybe they simply go to watch people die, and ferry them to the next world.
You cruelly, cruelly hinted at monsters in the Bestiary 3 but have not delivered. The different Leshies, the different Behemoths... so many, I want them all!
Rules in the back of the Bestiary 4 to make vermin animal companions (we have a vermin-companion druid now, covering the first 2 Bestiaries, but we have nothing for the new vermin introduced in the Bestiary 3).
A Leshy you can take as a familiar. Rules for taking a Leshy as a... Leshy Companion in place of an animal companion. Rules for a Clockwork familiar. Rules for vermin familiars.
Some weaker Demodands--including one you can take as a familiar!
Dragons based around unusual concepts; a feathery dragons, or one who is insectile or an arachnid dragon. A tentacled-dragon.
Space dragons!
More of the monsters and races from Distant Worlds.
More horrors from the Dark Tapestry, one of which can be taken as a familiar.
More good outsiders! Something to show that good is not being crushed by the darkness!
A good-aligned outsider that uses darkness.
Take back what you said about Agathions not having hyena forms; hyenas have very caring, close-knit family communities. They take proportionally longer care of their children than any other animal (other than humans), and are not deserving of their nasty reputation at all. Lions steal hyena kills more than the other way around.
Golems of abstract concepts solid form.
A 2-dimensional monster.
A monster that wields advanced, quantum mathematics for unusual attacks.
A cute monster, that is actually horrifically evil and malevolent. They tend to act friendly, slowly introducing suffering until they reveal themselves as the monsters they are--then they leave, after making their victim destroy his life.
A monster that is from the future, trying to stop something from happening.
Alternate Shikigami; in myth, shikigami aren't clearly defined, so make some other types than the... rock... thing in the Bestiary 3. Honestly, most of the depictions I've seen of them were like spirit animals, or were made of paper.
A template for creatures made of paper (I think paper-creatures fit the concept of onmyou well, don't you? Fits for a more oriental-feeling campaign).
A creature with an 'acid' attack that is actually a base, bypassing acid resistance.
Chemical creatures.
A construct with a philosopher's stone as it's 'heart'.
The Ghost in the Machine. Well, not a ghost, but a spirit/outsider, designed for technology and machinery.
An angel with guns.
A plant that was once a different species, but it ate a clockwork creature, and now grows organic gears as a clockwork-plant. With spikes, and explosives.
A monster based off of the fungus 'cordyceps'. It takes over an insect's mind and controls its body to make it go someplace where the fungus can release its spores to capture more insects. Insidious and evil.
A being (more accurately, a race or template) or a creature that was stillborn, then had resurrection magic used on it, or was pumped so full of positive energy that it jolted back to mostly-life. Not evil, but odd and has difficulties fitting in. An unusual being.
