Spice Girl's first and later changed appearance at the end of Chapter 499
Spice Girl (スパイス・ガール, Supaisu Gāru) is the Stand of Trish Una, featured in Vento Aureo.
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. She also openly acknowledges Giorno Giovanna's role in influencing Trish's spirit into maturing, referring to him as a mysterious individual.
Her battle/Stand cry is "WANNABEEE~" (in reference to the Spice Girls' debut single).[citation needed]
Softening: Spice Girl is able to soften any material. Any object that is softened by the ability is indestructible to anything aside from the Stand herself. Said objects gain consistency and elasticity akin to rubber or putty, unable to even be punctured by any force including sharp objects. 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, causing the projectile to merely flatten upon contact.
Super Strength: Spice Girl has considerable strength, and claims she has the force of a vise. 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 in an attempt to destroy it. When used against objects that have been softened, they will break cleanly. Another example can be seen when Spice Girl breaks off the front of a plane by rapidly punching the walls and roof of the cabin.
