Purple Haze is a humanoid Stand of a height and build similar to Fugo's. Its face and body are patterned by horizontal lozenges of alternating shade, and armor pieces are present on its shoulders, elbows, and knees. It has spikes along its back. In the anime adaptation, Purple Haze's design is slightly changed, with the Stand receiving a long, flowing cape.
Its lips and appendages are loosely stitched, and its eyes have distinct irides with miotic pupils. On its head is a helmet inspired by Roman design[1] with a transparent visor in the approximate shape of a beak.
Befitting its name, all media featuring Purple Haze portray it as a checkered purple and white Stand.
Personality
Purple Haze has a hair-trigger temper and will act aggressively if its user is somehow absent. Despite its tendency to drool uncontrollably, it is also a "neat freak" and will obsessively clean the very drool off itself until it bruises its own arm. It is stated that its temper, cleanliness, and viral ability and desire to "clean" everything is similar to Fugo's own personality.[2]
In battle when punching its opponents, Purple Haze shouts, "Ubashaaaa!!!"[2]
Ability
Because of its deadly ability and its potential for indiscriminate destruction, Purple Haze is rarely used by Fugo as stated by Abbacchio.[3] However, it is undeniably a powerful close-range Stand.
Killer Virus Infection
Purple Haze is an unstable Stand that contains a particularly deadly, flesh-eating virus in each of the three bulbs on each of its hands.[2]
A virus inside of Purple Haze's fists can decompose flesh at a fast rate
When a bulb breaks, usually because Purple Haze punches something, the virus is released and surrounds the Stand. Anything that enters its range is infected, and an adult human being will melt into organic goo within 30 seconds as the virus rapidly multiplies within their body, overrides their metabolic functions and makes them rot from the inside.[2] In the case where Purple Haze is unable to shatter the bulbs through direct contact, it can release them from its hand like a pressurized gun.[4]
Because the virus indiscriminately attacks friends and foes,[2] it makes Purple Haze a very dangerous Stand for Fugo's allies. Even its user isn't immune from the effects of the virus.[5] Fortunately, the range of the virus is short and it is weakened by light from any source be it sunlight or a lamp.[2]
Despite the deadly nature of the virus, an organism with the right antibodies can survive Purple Haze. Thus a snake Giorno creates inside the range of the virus has naturally created antibodies to survive; Giorno uses these same antibodies to make a vaccine and save himself from being devoured.[4]
