Pinkie is a weird little freak and I love him. Also, he's a man because I can't imagine Jojo's without beautiful men lol. He works as a DJ at Vinyl Scratch's club, Hot2Trot, in the shadier parts of Ponyville, and he switches between being as bubbly and sugary sweet as his canon counterpart, and a total vicious MONSTER with a violent temper. I based him a lot on Narancia lol... I'm especially proud of his harness; I think it looks both like acceptable enough stylized horse tack AND a slutty strappy harness top lol. I love him.
Pinkie's Stand is [Twist and Shout], named after the single by The Top Notes, famously covered by The Beatles. [Twist and Shout] allows Pinkie to give orders to others that must be followed, though these actions must be physical in some way, and he can't give the same order twice. For example, if they were fighting a Stand that activates on sight, Pinkie could order a teammate to go blind to avoid activating it. Each order lasts a few seconds, or until the order has been completed. [Twist and Shout's] range is based on earshot, so its purely a support Stand with little to no combat ability to speak of. Pinkie is capable of fighting other ponies, but needs help when up against combat oriented Stands.
