Devil Fruit time

Diagnosis results I have created a Non-Canon Devil Fruit for you, VinizRF. Your Devil Fruit is called the "Shadow Shadow Fruit".

The powers and abilities of the Shadow Shadow Fruit allow you to manipulate shadows in various ways. You can create and control shadows, making them solid and tangible. You can use shadows to attack your enemies, creating shadowy weapons and projectiles. You can also use shadows to hide yourself and become practically invisible.

As for Haki, you have awakened the Observation Haki. This gives you the ability to sense the presence of others, even if they are concealed or far away. You can also predict the movements and intentions of your opponents, giving you an advantage in battles.

In terms of strength, you are considered to be quite powerful. Your control over shadows and your proficiency in using Observation Haki make you a formidable opponent. You have the potential to become one of the strongest fighters in the One Piece world.

Remember, this is a Non-Canon Devil Fruit, so it does not exist in the official One Piece story. But in this hypothetical scenario, you would be a force to be reckoned with!
