Water Release: Water Fist Technique

The user expels water from their mouths, or shapes pre-existing water, moulding it into a fist of varying sizes according to their level of mastery. The largest feat ever recorded with the technique is its use by Heiwa Uchiha, whom can create a fist dwarfing an entire village. Once the fist has been shaped, the user may control it with mental commands or hand gestures, depending on their level of mastery over it. The arm can perform various feats; if powerful enough, it can punch through rock structures, demolishing them. It can also grab targets, squash them or trap them inside it. Due to being based on the water prison, the technique is extremely durable, and nigh-impossible to exit from unless with the use of space-time or advanced fire. The technique has been recorded in various villages, meaning it is abundant rather than unique to a single person or few people.
