Toro Toro no Mi

The Toro Toro no Mi, is an anime only Devil Fruit, that gives its user the ability to turn into a liquid-like substance. Toro means liquid and the substance the user turns into isn't water. It was eaten by Honey Queen.

Strengths and Weaknesses
The Toro Toro no Mi allows it's user to transform in an unknown liquid, enabling it's user to flow through small spaces and attack with liquid blasts. Unlike other Logia types, the Toro Toro no Mi can't generate liquid seperate from the user's body, as the users limbs reformed from the liquid used for long range attacks.

The user also has no effective physical strength when in liquid form, and cannot transform back into their normal form if they are in a space that their normal body can't fit in. Because of these flaws, Nami was easily able to captured and sealed Honey Queen in a bottle while she was in her liquid form, who was unable to escape.

Also, even though Devil Fruits transform the user's clothes along with their body, she always leaves her clothes behind while she transforming into liquid. Other than that, the user is also affected by the standard Devil Fruit weaknesses.

Usage
Even though this fruit's power is inferior for a logia-class, Honey Queen can still use her power as a quick attack, as seen when she kidnapped Sanji. She launched a wave of her liquid to wash against the Straw Hat Pirates, causing Sanji to fall off the air balloon. She also transforms into the liquid for quick movements, and to move through a pipeline.
