Dogumaru appears to be a half-human, half-horse clay statue bearing the green gem often found on Relic enemies. He attacks by charging a pulse before firing it at the ground, creating a green explosion. His red eyes glares during his attack animation.
This enemy behaves like a stronger version of Manic King Dragon Cat, having more health, damage, an already high standing range of 500, and an Omni Strike that reaches up to 700 range. Due to his reach, he is difficult to attack safely. His main weakness is his somewhat low DPS, but keep in mind up to 3 of him are spawned on a timer in Primitive Souls. When introduced into 2~3♛, his danger increases significantly and is no longer possible Uberless with any degree of simplicity.
Thought to be a haniwa*, but in fact he is a dogū*. An unfortunate warrior who was mistakenly attached to the lower body of the horse dogū that had fallen beside him. *Haniwa and dogū are types of ancient clay figurines. Haniwa in particular used to be buried alongside the dead.
This enemy always appears at 100% strength magnification.
He is based on ancient Shakōkidogū figurines, the most recognizable form of dogū.
The word maru in Dogumaru's name can mean "full" or "whole" in Japanese. This may refer to how being attached to a horse statue's lower body has made Dogumaru complete again, as Shakōkidogū in real life are seldom found with all of their limbs intact.
For a few reasons, Dogumaru could potentially be a nod to Hanimaru from the children's television program Ōi! Hanimaru:
Both combine the name of an ancient Japanese clay figurine with 丸 maru (Hanimaru is haniwa, Dogumaru is dogū).
As an enemy, Dogumaru's Japanese description mentions that he was thought to be a haniwa.
Hanimaru is usually seen with his horse haniwa Hinbei, while enemy Dogumaru's Japanese description states that he was mistakenly attached to the lower body of a horse dogū that had fallen beside him.
