|“||That which is soft is more unbreakable than any diamond!||”|
Spice Girl is a humanoid Stand of a feminine figure, resembling Trish in proportion.
She has several mathematical signs on her body: Two plus signs rest on her shoulders, two on her elbows and one on her forehead, followed by a division sign on her brow and a multiplication sign on her crown. Her face is without a nose, and has black streaks running vertically across her eyes.
Spice Girl seems to have a consciousness separate from Trish, and has even been seen giving her advice during battle. Of note is the fact that, unlike most Stands, Spice Girl provides a name for herself. Likewise, Trish refers to the Stand as "her" and "she", unlike the common "it".
Trish first becomes aware of Spice Girl's existence due to the Stand actually speaking to her when she was panicking over what to do about Notorious B.I.G.. Her attitude and strength of character are also reminiscent of Trish's first appearance.
Softening: Spice Girl is able to soften any material; even the hardest of diamonds. This can provide a cushion for a softer landing, or create a backlash when the object returns to normal (like a catapult when it is pulled and released). She can even soften moving objects like bullets.
Super Strength: Spice Girl has considerable strength. While moving slower than a clock's second hand, she was able to use a pipe to stab and section Notorious B.I.G. into pieces. When used against objects that have been "softened", they will break cleanly. An example of this can be seen when Spice Girl breaks off the front of a plane by rapidly punching the cabin.
- When Spice Girl was first hinted at in Chapter 499, she had a bird or dinosaur-like quality to her, illustrated by her large claw marking left in the ground. By the time she was fully shown in Chapter 537, her design was apparently changed and the claw was gone. Despite this, a similar claw marking appears imprinted on a passenger seat Trish lays her hand on when the Stand was introduced, implying it to be an unexplained phenomenon separate from Spice Girl's body.
