The go-zu  oni  makes one  attack  with its gore and one  attack  with its greataxe. \n'b'  Gore ( Oni  Form Only) .  Melee Weapon Attack : +8 to hit, reach 5 ft., one target.

The target must make a DC 16  Dexterity  saving throw or be  restrained  by the molten copper as it begins to harden. The target takes 1d6 fire damage at the beginning of each of its turns until it breaks free (escape DC 16). \n'b'  Change Shape . The go-zu  oni  magically polymorphs into a Small or Medium humanoid or beast, into a Large giant, or back into its true form. Other than its  size , its statistics are the same in each form. The only equipment that is transformed is its greataxe, which shrinks so that it can be wielded in humanoid form. If the  oni  magus dies, it reverts to its true form, and its greatsword reverts to its normal  size . \n'b'\n'b' ABOUT \n'b' Go-zu  oni  are outwardly similar to other  oni , with powerfully built humanoid bodies of prodigious  size , but with the heads of beasts. A typical go-zu  oni  is 9 to 10 feet tall and weighs between 500 and 1000 pounds. Their skin is typically orange, gray, purple, or brown, and they favor wearing fine robes and well-crafted armor to mark their perceived station as creatures of power, wisdom, and cleverness. \n'b' Most  oni  on the Material Plane pursue their plans for power in the mortal world, but the go-zu  oni  retain more of their connection to their ancient progenitors in the Outer Planes. They are often encountered near planar gateways, whether intentionally created by diabolists and death cults of all kinds or simply naturally occurring thin spaces in the planar fabric. They travel back and forth between worlds and often consider themselves guardians and guides of the paths of the dead. They may be the first creatures encountered by planar travelers venturing into the realms beyond, and if not precisely benevolent they can be impartial servants who simply assist with the spiritual journey. \n'b'  Go-zu and Me-zu . While many mortals see beast-headed giants and flee in terror without bothering to learn more about them, there are a variety of different beast-headed giants that mortals all lump together as go-zu  oni . In fact, the go-zu  oni  (also called niutou) specifically refer to those  oni  with heads like horned bulls or oxen. \n'b' Their most common kin, the me-zu  oni  (also called mamian) have heads like shaggy horses. Others are reported to have heads like predatory beasts, monkeys, or even insects. Whether this indicates a specific caste or rank is unclear but go-zu and me-zu  oni  often work together as messengers, battle leaders, guardians, and more, and their game statistics are identical. \n'b'  Soul-Stealers . Many among the go-zu  oni  cleave more closely to their fiendish ancestors in their hellish realms, and they look for opportunities to enslave and kidnap mortals, spiriting them away into torment and judgment in the Lower Planes.'
