Hito Hito no Mi

The Hito Hito no Mi, also known as the Hito Hito Fruit, is a Zoan type Devil Fruit that allows its user to turn into a human hybrid and a full human. In the 4kids dub, it is called the Human Human Fruit. It was eaten by Tony Tony Chopper.

Strengths and Weaknesses
The fruit's major strength is that it gives it's user the ability to turn into a human and a human hybrid. In the case of Chopper however, it has given him much more. The fruit has given him the ability to understand and communicate human language. The fruit has also given Chopper the ability to perceive concepts such as medicine that a normal reindeer wouldn't normally comprehend.

The fruit is further strengthened by the use of the Rumble Ball. This drug allows Chopper to access other forms of varying human and reindeer proportions. The Rumble Ball however is not a thing that should be applied as the consequences to the powers of the fruit and the user himself can be quite disastrous.

The major weakness of the fruit, in the case of Chopper, is that forms it gives him are often mistaken for something else. Examples include his human form being mistaken for a gorilla and his human hybrid form being mistaken for a tanuki. This is what originally alienated Chopper from both deer and humans alike. However, despite this, one advantage of this is that Chopper can easily hide from enemies whilst in a form they haven't seen before. Other than that, the user is susceptible to standard Devil Fruit weaknesses.

Usage
The powers of the fruit have been used by Chopper for a variety of ways. Chopper mostly uses them in order to interact and understand humans. He has used them to a point that he is able talk in human whilst in his normal animal form. In the midst of battle, Chopper has also used his Devil Fruit powers in order to fight enemies with the strength given by the Devil Fruit. With the Rumble Ball, he developed, Chopper can further use his Devil Fruit powers to an extent unlike most other Zoan Devil Fruit users.

Normal Transformations
Like all Zoan Devil Fruit users, Chopper posses the ability to turn into three forms. These forms are called Walk Point, his normal form, Brain Point, his human hybrid form, and Heavy Point, his human form.

Walk Point
Walk Point (脚力強化 (ウォークポイント)): This is Chopper's form as a normal reindeer, useful for general travel on foot. Being his original form, this is apparently the only form that actually ages as Chopper grows older. Despite reindeer physiology possessing no vocal cords capable of human speech, Chopper is able to speak the human languange in this form thanks to the Devil Fruit's powers. During battle, Chopper usually uses this to run across the battlefield to dodge an enemy's attack or otherwise. During any other time, Chopper is completely disguised in this form as he usually looks like pet. While Chopper looks like a typical reindeer in this form, the only thing differentiating him from other reindeer, other than his clothes, is his abnormally blue nose which is mostly noticed by other reindeer. This form is called "Sprint Boost" in the 4kids dub.

Brain Point
Brain Point (頭脳強化 (ブレーンポイント)): Chopper's usual and human hybrid look, with a small body and large head. He is smarter in this form, and also inexplicably cute. When fighting against enemies, Chopper usually changes this form immediately in order to dodge an attack due its small size. In addition, he can scope out an enemy's weakness in this form, while he is under the influence of a Rumble Ball. In the 4kids dub it is named "Brain Boost". This is also the form where he does his best strategizing, as he can utilize both human intelligence and reindeer sensitivity at the same time. Chopper is often mistake for a tanuki in this form. This is also the only form that is posted on Chopper's wanted poster. However due its physique, Chopper was easily mistaken for a pet by the authorities and hence his current bounty.

The named Devil Fruit techniques Chopper can use while in this form are as follows:


 * Scope (診断(スコープ)): Can only be used when in Brain Point form and after eating a "Rumble Ball," a move in which he concentrates and scans his opponent to find their weakness. When this move was first shown to Luffy, Luffy assumed that Chopper would fire a laser against Chessmarimo. The reasoning behind this assumption is because the way Chopper holds his hooves up to perform this move visually looks like a Dragon Ball move, the Kikōhō technique most likely in question. In the 4kids dub, this is called Rumble Scope.

Heavy Point
Heavy Point (重量強化 (ヘビーポイント)): Chopper's "human" form, which gives him a werehuman-like appearance and height. In this form, nearly all of Chopper's reindeer physical characteristics are gone. Only Chopper's blue nose and parts of his fur remain. This form also imbues Chopper with super-human strength which comes handy in battle or otherwise. Chopper usually uses this form to try to blend in with other humans, but it is often mistaken for the Abominable Snowman or some other similar hairy hominid cryptid. This form is also mistaken for a gorilla. In the 4kids dub, this called "Heavy Boost". While his voice stays the same in all forms, his voice becomes deeper in this point in the 4kids English Dub.

The named Devil Fruit techniques Chopper can use while in this form are as follows:


 * Heavy Gong (重量ゴング): A basic punch to the face that can be used by Chopper in Heavy Point. This was first seen being used on Kumadori.


 * Robi-Cho Suplex (ロビッチョスープレックス): A technique that can be done by Chopper and Robin while Chopper is in Heavy Point. After Chopper grabs an opponent in Heavy Point, Robin sprouts leg after leg under Chopper's feet with Pierna Fleur. When a desired height is achieved, Chopper would jump off his "stilts" and crush the opponent's head in a suplex move. This was first seen being used against Hogback.

Rumble Ball Transformations
Along with his normal forms, Chopper has added on to these by use of the Rumble Ball (ランブル). This yellow jaw breaker-like drug gives him several more transformations for three minutes by "distorting the wavelengths of transformation". These forms are most effective in battle against difficult enemies. While Chopper gains an edge in battle with these and the Rumble Ball, the number of the Rumble Balls Chopper can take in under six hours must be carefully monitored. If Chopper takes two under six hours, he loses normal control of his bodily transformations. If he takes three, Chopper turns into a form deadly to both himself and others around him.

Jumping Point
Jumping Point (飛力強化 (ジャンピングポイント)): Chopper keeps his reindeer legs in a human-like form, which allows him to jump long distances. This form is perfect for avoiding enemy attacks by allowing Chopper to dodge them by jumping high up in the air. The distance from which Chopper can jump into the air in this form can be quite remarkable that it can give him a massive advantage in height against opponents. However despite it's jumping capabilities, the form is slightly useless against enemies that can move in mid-air too and reach him. Chopper also doesn't have so far any attacks with which he can perform in this form. This form has mostly been used solely for evasive purposes only. In order to attack, Chopper has to change to another form. This is called "Jumping Boost" in the 4kids dub.

Guard Point
Guard Point (毛皮強化 (ガードポイント)): Chopper's fur grows out and covers his entire body leaving only his head and two legs visible. In this form, Chopper looks like an overgrown Chia Pet in this form. With this fur, Chopper is able to withstand against most outside attacks with this impenetrable shield. However while this form's defensive capabilities are high, it doesn't seem to allow Chopper to perform any sort of attack. So in order to attack, Chopper has to change to another form. This form's fur also can only withstand certain types of attacks. This means any attack that is too powerful for the fur to withstand can damage Chopper even while he is in this form. In the 4kids dub version, this form is named "Guard Boost".

Arm Point
Arm Point (腕力強化 (アームポイント)): One of Chopper's more powerful form, his fore-hooves become extremely muscular in a humanesque form. In this form, Chopper's fore-hooves become powerful enough to inflict a great amount of damage. They are capable of destroying a huge rock with one punch. They also have a certain ammount of durability as seen when they were slashed by Chessmarimo with a technique that was capable of destroying a wall. Chopper usually turns into this form in battles in order to deliver a powerful punch to knockout his opponent. In the 4kids dub version, this is called his "Arm Boost"

The named Devil Fruit techniques Chopper can use while in this form are as follows:


 * Kokutei Roseo (刻蹄桜(ロゼオ), Carving Hoof Sakura): Can only be used when in Arm Point form. Chopper punches the opponent with such a force that his hoof leaves an imprint in his victim that looks like a sakura petal. In the 4kids dub, this is called Reindeer Roundhouse. This technique was first seen being used to defeat Chessmarimo.


 * Kokutei Cross (刻蹄十字架(クロス), Carving Hoof Cross): Can only be used when in Arm Point form. Another punching attack where Chopper hits his opponent with insane force, but this time he puts both hooves together at the right side of his body wrist to wrist. When he strikes he spreads his "toes" apart so that the imprint left in the opponent's body looks like an 'X'. This technique was first seen being used to defeat Gedatsu in Skypiea.


 * Roseo Metel (桜吹雪(ロゼオ・ミチエーリ), Sakura Snowstorm): Can only be used in Arm Point form and is currently Chopper's strongest attack. Chopper starts off by putting his hooves together on the right side of his body, as if setting up for a Kokutei Cross attack, then he runs or jumps torwards his opponent, and hits the opponent over his entire body with a barrage of Kokutei Roseo punches. The hoof-mark imprints look like a large group of falling sakura petals. This was first seen being used against Kumadori however it wasn't powerful enough to defeat him. "Metel" (Метель) is Russian for "snowstorm."

Horn Point
Horn Point (角強化 (ホーンポイント)): A form similar to Walk Point but with larger and sharper antlers. In this form, Chopper's human arms also become more bulkier in order to compensate with the large load upon his head. With these huge antlers, Chopper can use them for a variety of ways, such as using them as a large shovel. Chopper first uses Horn Point against the Mr.4 team, labeling it his "most powerful form". In the 4kids dub version it is called "Horn Boost".

The named Devil Fruit techniques Chopper can use while in this form are as follows:


 * Hissatsu Uso-Cho Hammer Suisei (必殺ウソッチョハンマー水星, Sure-Kill UsoCho Hammer Comet): A combo attack between Usopp and Chopper, Chopper transforms into his Horn Point form and Usopp uses Choppers antlers and a large rubberband as a slingshot to fire the hammer Usopp uses for his Usopp Hammer attack at the opponent with tremendous force. This was first seen being used against Mr. 4. In the 4kids dub, this is called Hammer Shooting Star.


 * Roseo Colonnade (桜並木(ロゼオコロネード), Sakura Colonnade): Can only be used in Horn Point form. An attack used when Chopper is up against several opponents at once, he chases his opponents and tosses them in the air with his horns. When they land their head ends up embedded in the ground and their body sticking straight up out of the ground.

Unnamed Monster Point
The consumption of three Rumble Balls in under six hours gives Chopper an additional Rumble Ball transformation, in which he is standing similar to Heavy Point, but possesses an oddly misshapen head and antlers, as well as an incredible (likely more than twenty feet, or about the size of an office building) increase in height and strength. Chopper's fur is also lengthened in this form. Chopper also loses all consciousness and goes on a berserker rampage in this form. Also, this form appears to be a combination of all Chopper's points, not including Brain Point (Heavy Point stance, Arm Point strength, Walk Point speed, Horn Point horns, Jump Point legs, and Guard Point hair). The limits of Chopper's strength in this form are unknown, but while in this form, he is capable of defeating very powerful opponents such as the CP9 member Kumadori.

The form also has hands unique to all the others; he retains five fingers analogous to a human's, but each digit is replaced by a thick, long, black hoof in the shape of a finger. Doctor Kureha told him after he had used it for the first time, that he had leveled an entire village on Drum Island while in this form. Kureha also commented on this form being that of a true monster; a danger to friend, foe, and even Chopper himself. According to Zoro's observation, this transformation appears to be lethal to Chopper, as the amount of energy needed to maintain the form is too much for his body to handle, thus it is only used as an absolute act of desperation.

The only known way to end this form is by placing Chopper into the sea (which, as he is a Devil Fruit user, instantly negates his powers) as the amount of time this form lasts is unknown; this is perhaps how Chopper's Monster Point was stopped during the first time he used it, and the aftermath is similar with him unable to move.

While this form has yet to be given a proper name, it is refered to as Monster in chapter titles. In One Piece: Unlimited Adventure, this form is called Overlimit Chopper. It is also unlockable in the game as a character in VS Mode, and is playable in the main story if Chopper dies in a boss battle after consuming a Rumble Ball.

Trivia

 * It has been said that if a human were to eat this fruit, they would remain the same, but would simply be enlightened but would be unable to swim.
 * In a response to a fan who was slightly confused on how Chopper was clinching his hooves in a fist, Oda showed how Chopper would perform Rock, Paper, and Scissors with his hands. His first drawing showed how Chopper would normally perform the said actions with normal human hands. The second one however showed how Chopper would do them with his hooves.


 * Although Chopper shouldn't eat more than one Rumble Ball within six hours, in the filler part of the Davy Back Fight he took two right after another in the "Hit and Deadball" game. Thus, this is one of the major plotholes Toei created. However because this was done before Oda got to that part in the manga, they had no way of knowing.
