Empress is a Stand bound to its own user's blood, first appearing as a small drop of blood from Nena. Once the blood drop hits a person, the true Stand is revealed. Empress starts as a small, itching wart,[1] similar to a bug bite, that swells as it grows and eventually develops humanoid features.[2] Moreover, another similar wart can be seen on Nena's tongue without explanation.[1]
When it is developed, Empress looks like a small woman growing out of the victim's flesh who possesses a two crests on her head and a shawl.[3][4]
In the colored manga and anime, Empress is portrayed as being red. However, the colored manga also portrays it as having golden crests and clothes in contrary to the anime, where Empress is a brownish color.
Personality
Seemingly relayed from Nena, Empress comes off as a sarcastic, disrespectful, mocking Stand, constantly insulting Joseph (the unlucky host)[2]. It represents The Empress Tarot Card, which symbolizes the growth of new life (hinting the nature of this Stand).
Its design is based on a rearranged Indian Buddha statue.[5]
Ability
Empress is a exceptional hybrid between flesh and Stand that is both dangerous and frustrating to get rid of if planted on its victim.
However, its simpleness and mediocre physical prowess allow even Joseph's Hermit Purple to defeat it.
Parasitism
Once grown, Empress will be dangerous to its host
Empress must first be planted into another person through direct contact with Nena's blood, but can otherwise be controlled by her remotely[6].
The zone splattered with blood will develop a fleshy bud, similar in appearance to a wart.[1] Empress will then continuously grow out of the victim's flesh as long as it feeds off exterior sources relative to it's size, be it small insects, fruits or whole chickens. The Stand eventually reaches a humanoid form[3] and during the whole process, Empress will attempt to hinder and eventually kill its host. For instance, it framed Joseph as a murderer, then, when it grew arms, bashed him with pots and tried to drive a nail into Joseph's neck.[3][4] Nena can eventually use the victims as a disguise by hiding inside them.[4]
Empress is a mix of the victim's flesh and a Stand and takes properties from both. Thus, it can be heard by someone but will be seen as a mere wart by ordinary people,[3] and only a Stand can harm it, though being coated with tar can immobilize it.[4]
