Notable Attacks/Techniques:

- Cyclone Grenade: River's hand is covered with wind aura that allows him to execute a very high fast fist/create a small whirlwind. This attack is more powerful than a hand grenade.

- Mach Fist: River unleashes a powerful supersonic punch that can release an invisible shockwave to strike the enemy from distance. Compared to his other technique, the shockwave of Mach Fist isn't as powerful, albeit capable of knocking out weaker characters with a single attack.
