The surname Inuzuka literally means "House of Dogs," a powerful clan back in the olden days that worships dogs. To read more about this, please hop on here.
Moving on, the name "Kiba" literally means "fang." The following will include the kabalarians' analysis on this name. Just tell me how DEAD ON ACCURATE they were, won't you?
While the name Kiba creates the urge to be creative and original, we emphasize that it causes a restless intensity that defies relaxation. This name, when combined with the last name, can frustrate happiness, contentment, and success, as well as cause health weaknesses in the solar plexus, and tension or accidents to the head. Your first name of Kiba has given you a quick, analytical mind. You are creative, versatile, and imaginative.
However, independence, positivity and the urge for action and progress are such strong forces in your nature that you find it difficult to control them. You feel happy as long as headway is being made, but as soon as you are obstructed or your individuality and freedom of action are restricted, you experience an intense nervous reaction. Moods of depression can result during which you become sarcastic and stubborn in your attitude toward everyone, especially to those in closest association with you.
Personally, I thought that was one of the most accurate "Kiba" description without even knowing the boy(, and that makes my efforts of going through the whole manga, chapter by chapter, become useless). But, there you have it; the power of the kabalarians.
Unlike N-Kiba, WR-Kiba is actually a wolf in human form. Even if N-Kiba does have a lot of animalistic characteristics, he is still full-blooded human; he just spends an unatural amount of time with dogs. Otherwise, these two have no other things similar; WR-Kiba is a very calm and isolated person, so you cannot really put these two on the same pages besides the fact that they have the same name.
Put these two in a vacant room and we'll have a wild party, don't you think? Both raised in an animalistic enviroment, specifically in the canine category, they would surely battle eachother to submission. This is a part of a thing called the "alpha" of the group, where two male dogs have to show which one whose boss.
