So-Shi is a is a Goliath-class boss unit in NieR:Automata which makes use of its surroundings to gain advantages in battle. Examples include climbing walls to remain out of reach from opponents melee attacks while it heals, or electrocuting pools of water to create deadly fields of electricity.
A multi-legged, Goliath-class machine lifeform equipped with two massive blades. By emitting energy from the tips of its legs, it can move about as though gliding across the ground. The unit's sides serve as weapon racks that can launch missiles and other projectiles, while additional plating attached to the legs reinforces its weak armor. When the situation demands it, the unit can purge its plating and transform into a spherical form capable of spin attacks.
Its name is the Japanese reading of Zhuang Zhou (荘子), an ancient Chinese philosopher.
