The Kuma Kuma no Mi, Model: Black Bear (Kuma being Japanese for Bear) is a Zoan type Devil Fruit that grants the user the ability to transform into a Black Bear or a Black Bear-Human Hybrid.
Strengths and Weakness
The Kuma Kuma no Mi, Model: Black Bear's biggest strength is that it allows the consumer to turn from human to black bear, or a human-black bear hybrid. The consumer adopts the abilities of a black bear as well as superhuman strength in their hybrid form.
Unlike other hybrid forms which increase the speed of the consumer, the Black Bear model, despite being smaller then most bears, decreases the speed. However, the strength is much more then that of a normal hybrid. Standard Devil Fruit weaknesses apply.
