Blood's Clenched Fist (血竜の握り拳 Chi no Nigirikobushi) is an extremely dangerous technique and one that takes the advantages of the Blood Control technique to its optimum level. The control and manipulation of blood within a person's body can have many different effects. For instance, Blood Control can potentially be used to crush or disrupt the activity of a victim's internal organs.
However Blood's Clenched Fist requires exceptional concentration and precision by Ranma himself.
