Katsuo Uchiha

Name: Body Replacement Technique
Rank: E-rank
Type: Ninjutsu
Element: None
Range: Mid (7m)
Handseals: Tiger → Boar → Ox → Dog → Snake
Description: With this technique, users replace their own body with some other object, generally with a block of wood, the moment an attack lands. This creates an optical illusion, making the enemy think the attack was successful. From this, the user can use the lapse in the enemy's attention to attack or flee from the battlefield. Explosive tags can be attached to the replacement for an added surprise. It's a basic ninjutsu even taught at the Academy, but it's a useful art that can be applied in variety of situations.

Name: Clone Technique
Rank: E-rank
Type: Ninjutsu
Element: None
Range: Clone can travel up to 10m from user
Handseals: Ram → Snake → Tiger
Speed: Clones move at same speed as user
Description: A ninjutsu that creates an intangible copy of one's own body, without any substance. Since the clone itself doesn't have the ability to attack, and thus can only be used to confuse the enemy, it is mainly used in combination with other ninjutsu. It's a basic technique, but depending on one's ingenuity, it can be used effectively. The clones may not dissipate when they come into contact with something. These clones can be easily distinguished by persons with dōjutsu. A person with normal eyes can also distinguish the clones from the original, since the clones do not have shadows and will not disrupt the area around themselves with their movement (i.e. won't kick up dust, crush grass, etc.).

Name: Transformation Technique
Rank: E-rank
Type: Ninjutsu
Element: None
Range: Close
Handseals: Dog → Boar → Ram
Description: Given all the missions ninja are assigned to - battle, intelligence gathering, diversions - this is a priceless ninjutsu. It is typically used to change into people other than oneself, but one also has the ability to change into animals, plants, and even inanimate objects like weapons. This gives this technique an abundance of uses. The transformation of a skilled shinobi will be exactly like the genuine article, so it will be impossible to tell the two apart. On the other hand, a transformation performed by an inexperienced person will have obvious discrepancies. It will be impossible to deceive anyone with it. This is one of the most basic ninjutsu, as such most shinobi know how to perform it. The transformation technique is considered to be among the more difficult E-ranked techniques, since it requires constant emission of chakra while mentally maintaining the form. On top of that, the user would be, most likely, interacting with the environment. This puts mental strain on an inexperienced ninja. Thus the best way to determine if it is indeed a transformation is to cause this strain upon the user; though this is of course not always successful.

Name: Tree Climbing Practice
Rank: E-rank
Type: Ninjutsu
Element: None
Range: Close
Description: Tree Climbing Practice is a training method used to gain more skills with chakra control. This training involves focusing a fixed amount of chakra to the bottom of one's feet, and using that to climb a tree without using one's hands. If the stream of chakra is too weak, the user will lose their footing on the tree and fall off. If it is too strong, the user will be pushed away from the tree, causing the tree to break around the point of contact and the user will fall.

Name: Water Surface Walking Practice
Rank: E-rank
Type: Ninjutsu
Element: None
Range: Close
Description: This training method is used to gain better chakra control. To do this, the user has to be emitting a constant stream of chakra from the bottom of their feet and using the repellent force to walk across the water's surface. This technique is more difficult to master than the Tree Climbing Practice, because the amount of chakra that needs to be emitted changes constantly. It has also been shown that one can use their chakra to "skate" across the water surface, like an ice skater, instead of just walking or running. It is noted, that shinobi reach a state where they stand on water without even noticing it or basically even trying.
