Attacks
Emerald Splash: A long-ranged flurry of emeralds nobody can deflect (for real this time). Also more accurate and Kakyoin can choose if the emeralds disperse outwards or go in a straight line.
Coiled Body: HR's body and robe are made up of small, string-like membranes that can be controlled at will. These can be used for a variety of things.
Marionette Control: HR moves its coils (including those of its robe) into a person's body, controlling their limbs until HR is either retracted or until Kakyoin is finished controlling the victim.
20-Meter Radius Emerald Splash: HR surrounds the victim with its coils and unleashes an omni-directional Emerald Splash around the victim. These can move faster than The World/Star Platinum can stop time.
Emerald Barrier: HR disperses its robe into coils to surround either Kakyoin or a victim in all directions. HR is able to manipulate these coils however it pleases, allowing it to enter and exit the barrier, or even become a part of it altogether.
Pilot: Kakyoin can control HR farther than usual for up to 5 kilometers away. He is able to see with HR as well as his own vision, alternating between the two.
Stand-Catching Spear: HR sharpens one of its coils like a spear and jabs it at the victim at an extremely high speed. When used in succession, it will forcefully hoist out the victim's Stand. The caught Stand's abilities and appearance are revealed to Kakyoin and then negated for up to 8 minutes (subject to change based on feedback.
This is NOT a canon Stand and simply a concept I made up. If you have any (useful) feedback, I'd love to hear it!
