Artificial Devil Fruit

The Artificial Devil Fruit (人造悪魔の実) is a Zoan-class Devil Fruit artificially created by Vegapunk, and allows the user to transform into a dragon. Its classified name, if it has one, has not been revealed yet. It was consumed by Momonosuke.

Appearance
The Artificial Devil Fruit is an apple shaped fruit with a long stem that curls at the end. It is rather small compared to other Devil Fruits, and due to being man-made, its patterning is also different: instead of swirls covering the fruit, it has ring patterns.

Unlike a natural Devil Fruit, it does not seem to have an unimaginably horrible flavor that one would describe as to the point of taking poison, as Momonosuke ate the entire fruit in bites without recoiling at the very least.

Strengths and Weaknesses
Being a Zoan-type, the Artificial Devil Fruit allows the user to transform into a dragon that bears a resemblance to a Chinese or Japanese dragon. In Momonosuke's case, his transformed size seems to be inferior compared to a natural Zoan-class Devil Fruit user's full-form transformation, as he is barely big enough to carry Monkey D. Luffy, a normal-sized human, and his clothes seemingly disappeared completely when he changed. The user also gains the ability to generate semisolid clouds that can be used as stepping stones, giving the appearance of flight. It is currently unknown whether or not Momonosuke's size in his animal form is due to his young age or an imperfection in the fruit, nor if it permits to morph into a hybrid form like normal Zoan.

The fruit was artificially created and was rumored to be a failure, so it seems to have flaws. A few moments after consuming it, Momonosuke transformed automatically, and he claimed that he does not know how to revert to human form. Later he was shown to be able to accomplish the task, albeit ending up completely naked. It is unknown if this fruit grants the general weaknesses as a natural Devil Fruit would.

Usage
Momonosuke originally ate the fruit on a whim to fight off hunger. He unconsciously used the ability to generate clouds to climb upwards, enough to run back up the many-stories tall garbage chute of Punk Hazard.

Trivia

 * This is the first man-made Devil Fruit shown in the series.
 * Due to the eel-shaped form Momonosuke takes on, Luffy jokingly believes this fruit allows the user to take on an eel form.
