Tama Tama no Mi

The Tama Tama no Mi is a Paramecia-type Devil Fruit that turns the user's body composition into that of an egg and allows the user to evolve into a chicken and become stronger when their body is destroyed. It was eaten by Tamago.

Etymology

 * "Tama" is short for "Tamago" (卵), the Japanese word for egg.

Strengths and Weaknesses
The greatest strength the fruit gives is the ability to regenerate from severe injuries that would normally kill a person by evolving from an egg to a chicken. The new forms the user gains also drastically increase their fighting ability, to the point where the second and final transformation makes the user a "true knight".

However, the user is left defenseless while regenerating. Also, it seems that their body is still composed of an egg even after evolving, as seen with Tamago's Viscount Hiyoko form. It seems that when the user evolves, they lose access to the ability to make human speech and can only make chicken noises. Otherwise, the user is affected by the standard Devil Fruit weaknesses.

Usage
With this fruit, Tamago's body is composed of an egg, giving him the name Baron Tamago (タマゴ男爵). He can then access two other forms known as Viscount Hiyoko and Count Niwatori.

Baron Tamago
Baron Tamago (タマゴ男爵) is Tamago first and main form. In this form, he gains an eggshell around his waist, and wields a shikomizue. He is also very proficient in rapid kicks attacks and wears tights that protect him from Electro. In this form, he often adds French words in his speech.

Viscount Hiyoko
Viscount Hiyoko (ヒヨコ子爵) is Tamago's second form. Tamago gains a beak and a pair of small wings, as well as two knives. Tamago is stated to be strengthened in this form, but any further abilities of this form have not been seen, as it was quickly destroyed by Pedro in its only seen usage. In this form, he often adds "Pyo" in his speech."Hiyoko" means "chick" in Japanese.

Count Niwatori
Count Niwatori (ニワトリ伯爵) is Tamago's final form. Its appearance is unknown, but it is stated to be a "true knight". In this form, he often adds "Cluck" in his speech. ""Niwatori" means "chicken" in Japanese.
