Xyloto

Stupid copyright friendly name: Cool Game
Xyloto is a defensive Stand with very limited reach. It's a black, angular humanoid being with sharp fins on the sides of its head, flat blocky forearms, broad shoulders, and dark green eyes. It functions as close to an immovable object as physically possible. While attacking, Xyloto yells "PARA."

Kinetic storage: Xyloto's primary ability is to store kinetic energy and release it later for its own attacks. The more energy it holds, the whiter it gets. Its maximum capacity is the strength of a full-speed freight train. Xyloto can also control how much energy is expended in each attack. It can expend all of its energy in a single punch(most likely a lethal move) or unleash several weaker attacks.

White Shadow: When Xyloto is storing the max amount of energy, it turns completely white. When white, it can send itself to a maximum of 12 feet from the User and expends all of the stored energy at the target. Once all the energy is used, steam is released from its joints as it turns from white back to black.

Destructive power: C
Xyloto's strength comes from extracting and storing the kinetic energy of the opponent's attacks or other actions. Its natural strength is not much higher than the User's.

Speed: A

Range: D
Xyloto is confined to 2 feet from the User's body. White Shadow is a situational ranged move and requires energy.

Durability: A
Xyloto can stop bullets and survive a collision with a large truck. It is also very thick-skinned and therefore difficult to damage. However, it's essentially defenseless against non-physical forces like fire, cold, and electricity.

Precision: C

Developmental potential: C
