Ooh, I've got a good one, I would say.
Stand Name: Right Round Act 1 (An Act Stand like Echoes and Tusk) (References a song I hope you know)
Ability: Spin Distribution
Description: Right Round Act 1 is a spherical Stand about 1.5 times the size of a steel ball. It's capable of imbuing any small object that it touches with Spin energy.
Appearance: A green, spherical Stand with light green accents around its sides, top, and bottom that look like Gyro Zeppeli's facial hair. Its face consists of two pink, long, oval-shaped eyes on the front and back.
Range: 12 Meters (It's much weaker in this state)
Limitations: It's generally very small and weak, and when it comes to direct combat, it's a little stronger than a steel ball with minimal amounts of Spin. Its main use lies in its ability, able to imbue small objects (as in no bigger than a small beach ball, which is a little bigger than RRA1) with a bit of Spin energy.
Attacks
Spin Induction: RRA1 touches an object with its spherical body, imbuing it with a relatively small amount of Spin.
User: Girevole "Jerry" Pallone
Occupation: Upper Secondary School Second-Year
Appearance: Has blonde hair and light green eyes. Wears a black school uniform with a light green tie with dark green polka-dots and black dress shoes. Casually, he wears a white tank top with a dark brown puffer jacket and khakis.
Character: At this point, he's just an Upper Secondary Student born in Naples, Italy, who just discovered his Spin capabilities, as well as his Stand. What he doesn't know is that when he was young, his parents knew that they would be found and killed by a certain individual who wanted to eradicate the last of the Zeppeli family. Before Jerry's parents were killed, they brought Jerry to an old family friend of theirs who lived in Rome, and gave Jerry to them.
Shortly afterward, Jerry's parents were murdered, and the Girevole Family adopted him. They knew his lineage, but never told him in fear of what would happen. Once, he was bouncing a ball against the wall while in detention (he was never the greatest student), and began focusing on it. Spin energy began to course through his arm into the ball, and as he threw it, it went as fast as a bullet and left a dent in the wall. At that moment, his Stand, Right Round, manifested before his eyes.
Jerry is the Great-Great-Great-Grandson of one of Gyro Zeppeli's siblings (not sure if he had siblings but I would assume so), and the last user of Spin.
Later Acts to come, as well as character development.
