Saru bakemono are the most idiotic of all goblinkind and they have many similar ape and orcish features. Many people say if an orc bred with an ape then the saru bakemono would have been born. But these strange creatures have been around before orcs or any goblinoids existed so many scholars speculate that they come from autochthonic birth or that they spring from the very earth itself.
War Beasts. Strangely enough when saru bakemono become dominated by goblins, orcs, hobgoblins or what have you they can serve as loyal war beasts and even as mounts for smaller humanoids. Goblins ride on their backs and fire arrows because the saru bakemono can climb vertically up trees with ease, They have strong and sharp claws that easily get a footing on the vertical surface of trees and even stone cliffs. Orcs and hobgoblins use them as savage ambush beasts to engage the enemy from the flanks or literally to fall upon them from cliffs and ceilings. orcs, hobgoblins and goblins also just eat them because they are so idiotic they do not even understand they are being taken to slaughter. They can be taught to listen to goblin or orcish commands and seem to follow simple instructions well, some can even speak but only in simple one-word utterances.
Variant: Kamikaze Saru Bakemono
Sometimes orc or hobgoblin armies even strap large explosives onto the back of the bakemono that when detonated can bring down a fortress wall. If the defenders see these they immediately fire fire-arrows at the beast to have it explode among its allies.
Death Burst. When the bakemono dies, it explodes. Each creature within 20 feet of it must then make a DC 12 Dexterity saving throw, taking 10 (3d6) fire damage on a failed save, or half as much damage on a successful one.
