Fusen Fusen no Mi

The Fusen Fusen no Mi is a Paramecia-class Devil Fruit that enables the user to inflate and deflate themselves and anything they touch at will, making them a Balloon Human (バルーン人間).

Strengths and Weaknesses
The main advantage of this fruit is the ability to expand anything balloon-style just by touching it. This includes humans and animals, and it is particularly effective on opponents since they are left almost completely immobile and are highly susceptible to wind. The user can take advantage of the aerodynamics of the expanded object, such as using it for a glider or a hot-air balloon. The user can also inflate a specific part of something without inflating the rest of it. However, the object will deflate over time.

Due to the fragile nature of balloons, it is very easy to injure someone who is in balloon form. They will not "pop" per se, but a similar reaction will occur. However, this also applies to the user, who must be careful when they are expanded.

The fruit can also be used to "deflate" solid objects, in a process similar to decay. The objects will maintain their texture, but their structure will often fold in on itself. This can also render opponents immobile. Like inflation, however, deflation is only temporary, with the deflated objects regaining air.

Although it is a well-known characteristic of balloons, the user cannot make what they touch pop (the Pamu Pamu no Mi, however, is capable of this deed). However, as mentioned before, a similar process will occur if the inflated object is attacked.
