Nekoken

The Nekoken, (貓拳, Cat Fist), also known as Cat-Fu, is a condition that Ranma Saotome is subject to when his fear of cats reaches an unbearable level, rather than an actual technique. If he were cured of his fear, this state would likely disappear. It is not a practically usable technique and beyond two times very early in the manga, it has only been activated against Maomolin but his general fear of cats is shown more frequently. Given his own increase in versatility and more efficient use of his inherent power, it is uncertain if this state would give him an advantage towards the of the series.

Overview
When Ranma was ten years old, Genma tried to teach him the Cat Fist. He tied fish sausages around Ranma and tossed him into a pit of hungry cats. However Genma had made the critical mistake of not fully reading through the description of the technique, which stated that such a method would only be used by an idiot. He tried to cure Ranma by repeating the process with dried sardines, salted sardines, and fish cakes, but these attempts had the opposite effect and only exacerbated Ranma's fear even more. Despite this, neither have sought or attempted to cure Ranma's phobia since.

When Ranma falls into his cat-like state, he starts acting like a cat, apparently using his power more efficiently by fighting like a ferocious animal, with swipes of his "paws" which have torn tree-trunks to shreds from a few meters distance. This does not seem to be the result of chi-blades, since no visual effect has implied it, while they were clearly distinguishable when generated by Herb, but rather powerful air pressure swipes, somewhat similar to those of Tatewaki Kuno or Ryu Kumon, but with far less shown destructive power than the latter. While in this condition, he even managed to disperse Cologne's Shark-Fist water blast, though it is uncertain how much she held back. However, he is mentally a cat, driven by instinct and of limited intellect or attention span, making (which will make him "drunk"), distraction (throwing something and saying "Fetch!" has proved enough to get rid of him) and complete lack of strategy major weaknesses of this form. Ranma cannot remember what he does when in his cat-like state. He has been brought out of the Nekoken by being doused with water, or by falling asleep in the lap of someone he trusts. This used to be an old woman who lived in the Saotomes' neighborhood, but is currently Akane Tendo. Also worth noting is that Ranma and Akane shared their first "kiss", while he was in this state, as he impulsively rubbed his face against hers.
