Jajanken: Rock

Jajanken: Rock (グー Gū) is an Enhancement Hatsu technique.

Description
Out of the three Jajanken, rock is a close-range melee attack that draws its power from the user's enhancement nen and has the strongest destructive power among the three because of the users natural affinity as an enhancer.

To perform the technique, The user starts by concentrating an immense amount of aura solely around their fists using Ko to increase the power of the technique and releases it in a devastating punch engulfed within an intense flame that results in incapacitating the target upon impact and simultaneously achieving victory.

The ability can be strengthened if the user builds his aura using Ren before attacking; he can also strengthen "Rock" by enforcing Zetsu and disallowing his aura to escape prior to his attack. However, the strength of the technique can increase exponentially depending on the user's mental state. The more intense the user's emotion is such as rage, the greater the destructive power of the technique becomes.

Despite the strength of the technique, "rock" has two major drawbacks. The first weakness is that it is considered too risky. As the user focuses their aura around their fist to increase power, it leaves less aura around the body for defense. The second weakness is that it takes too long to charge, giving the opponent an opportunity to attack before the user can finish the attack. However, the latter can be used as an advantage by incorporating feints. While the user charges the attack, those who have witnessed the how strong the technique can be will be more scared and likely to lose control when they see it coming as they'ed have a difficult time distinguishing between the fake and real "rock", allowing the technique to be more flexible.
