Kappa(Puppet)

Kappa is a made from the body of a shinobi whom Hotaru killed by poisoning. This man had possessed the rare Steel Release and thus the ability was retained by the puppet once Hotaru turned him into one.

Abilities

 * Kappa can utilise the Steel Release to make itself almost indestructible by hardening itself while it is launched towards opponents. The extreme weight generated by the puppet in this form makes it a type of wrecking ball when launched at a target. It can smash through buildings with ease in the form.
 * Kappa's most valuable ability is the ability to split its' body parts completely to attach itself onto Hotaru, effectively placing him in a silver suit of armour which is incredibly resilient and almost invincible.

Trivia

 * Kappa is a river spirit in Japanese folklore.
 * Kappa's ability to detach itself to protect its user draws inspiration from Iron Man's armour.
