Name in Japanese (translation): Hebi Hebi no Mi (serpent serpent fruit model Black mamba)
Capabilities: The Black mamba is known to inject on average 100-120 mg of venom in a single bite. As a result, so can the user of the devil fruit. The user can transform into a snake. The user can also manipulate his or her skin into the scales of a black mamba. The user can travel at 10-12 miles per hour at any given time and possesses the ability to paralyze foes with his or her venom. His or her venom can potentially kill, if the venom is not extracted from the body in 50 posts. The user of the fruit has a tendency to avoid fights and confrontation, and rapidly and viciously attack at any moment. The user can control not only the amount of venom he or she can inject into another, but what it can do, such as paralyzing the foe, giving the foe a recurring headache, or to limit the abilities of the respiratory system. The venom can only be injected if the user bites into another person's body.
Hybird: The user's teeth grow, the user's body starts to turn into a snake, in which its legs slowly meta morph into a black mamba's tail.
Full Form: The user can transform into a 8ft snake. His or her body will significantly become smaller, able to slither at 14 miles per hour.
