Deep Purple

"Made of smoke, it can manipulate atmospheric density. It can poison the air around it, change the air pressure, and detonate hydrogen and oxygen particles. However, its range is extremely short. The smoke that composes the Stand flows out of the skull-faced jar in the center." (In-Game Description)

"You are lukewarm and hate to be bothered to do much of anything, but are also dignified. You assert yourself easily, are thick-skinned, and have few worries. However, you are obstinate, contrarian, and hate to lose, often preventing it by aggressive means. You are overbearing and rebellious, but have talent to back it up." (Personality Evaluation)

Base Stats
In addition to these base stats, the Stand itself grants a bonus of Power +2 and Durability/Spirit +1. What Deep Purple lacks in raw power, it makes up for in utility. Despite having underwhelming Attack for a close-range Stand, it has a 1HKO attack unlocked at the very beginning of the game, and unlike most Stands which are mostly limited to one element, it learns a variety of wind, fire, ice, and non-elemental skills. However, a rather slow movement speed means Deep Purple lacks one-on-one potential. This makes it ideal for advanced players who know their way around the game's mechanics and can create strategies around their other team members.

Moveset

Author's Notes
''In short, "someone who finds things troublesome". The stand is a control type despite its short range, which is quite unfortunate. In fact, the user themselves are quite talented, so the stand is only for support. You could even say that, the user is someone who tries to rebel against their stand's capabilities.''
