Odotai Odotai no Mi

 The Odotai Odotai no Mi is a Paramecia-type Devil Fruit. It gives the user the attributes of the Chinese Zodiac animals and elements, but only one of each at a time.

Usage
The Odotai Odotai no Mi gives the user attributes based on the Zodiac animal and element that they currently "hold" (are imbued with). The held animal changes every day, at midnight, while the held element changes every 2 days, also at midnight. The held animal changes in the same order that the Chinese Zodiac changes (Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig), as does the held element (Wood, Fire, Earth, Metal, Water). Immediately upon eating the fruit, the user holds the first of each group, Rat and Wood. The next day they will hold Ox/Wood, then Tiger/Fire, etc.

The user will gain abilities based on the animal and element they hold. For example, if the user holds Ox/Fire, their upper body strength will greatly increase and they will be able to generate fire from their body. if the user holds Monkey/Water, they will become extremely agile and be able to manipulate water in a similar way to Fishman Karate.

The held animal and element also influence the user's personality, for example; if the user holds Ox/Fire, they will be thick, and easily angered, if they hold Monkey/Water, they will be mischievous and serene.

Weaknesses
The user suffers from standard Devil Fruit weaknesses.

When the held animal and element have conflicting effects on the user's personality, the user will typically have trouble maintaining their sanity and cognitive ability, and may even develop a split personality. The split personality may persist into the next held animal/element's, and will only resolve back into single personality through the user's will.
