Kagu Kagu no Mi

The Kagu Kagu no Mi is a Paramecia-class Devil Fruit that enhances the user's sense of smell, making it thousands of times stronger than a normal human's, as well as enables the user to create, control, and manipulate scents. In the Viz translation and Funimation dub it is called the Smell-Smell Fruit. It was eaten by LD.

Usage
As mentioned above, the user's sense of smell becomes incredibly strong, and they are able to detect scents from dozens of miles away. The user can remember a scent after smelling it, and will be able to track the source that scent from far away.

The other power bestowed upon the user is the ability to create, manipulate, and eradicate scents using their hands. The user can create an unlimited amount of scent from their hands, and can create any scent known to them. They can also give someone or something a completely new scent by touching them while using their powers for five seconds.

Strengths
A major strength of this fruit is its unrivaled tracking capability. Once the user catches his target's scent, he will almost always be able to find that target. This power has made LD a well-respected investigator in the Marines, as he has caught hundreds of pirates by tracking their scent. The target can always try to cover their scent, but the user will still be able to smell their original scent underneath. The user can learn other people's scents just by smelling something they touched.

The ability to create and manipulate scents is also a major asset to this fruit. The user can use this to overwhelm opponents with very strong scents, and has a range of scents in his arsenal that can instantly knock people out. Also, he has the psychological capability of invoking memories from scents, whether good or bad. If he is ever on the run, the user can easily change his scent to throw off his pursuers.

Weaknesses
A notable weakness of this fruit is that it has no direct offensive capabilities except for bad scents, and it can often easily be countered simply by plugging one's nose or developing a high tolerance for different scents.

Another weakness is that the user has no ability to block certain scents other than plugging his nose the old-fashioned way, and all the scents are enlarged to him, including the bad ones. To keep himself from succumbing to strong bad scents, LD always wears a face mask.
