Toro Toro no Mi

The Toro Toro no Mi is a non-canon Logia-class Devil Fruit from the second movie that allows the user to create, control, and transform into an unknown liquid substance at will. "Torotoro" is the sound effect for almost jelly-like substances. It was eaten by Honey Queen.

Strengths and Weaknesses
The Toro Toro no Mi allows its user to transform in an unknown liquid, enabling its user to flow through small spaces and attack with liquid blasts, as well as let physical attacks bypass the liquid body.

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 easily captured and sealed Honey Queen in a jar while she was in her liquid form, and thus was unable to escape.

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

Usage
Honey Queen basically uses her ability for quick and surprise attacks, as seen when she kidnapped Sanji. She launched a large wave of her liquid to wash against the Straw Hat Pirates, with enough force to cause Sanji to fall off the air balloon. She also transforms into the liquid for quick movements and evasive maneuvers, and to move through a pipeline for long distance transportation in a short time.

Trivia

 * This is the only known Logia fruit that belongs to a female character in the series.
