Sonny Zeppeli

''“Nothing beats it, Rose. Beethoven's Sonatas, Chopin's preludes... They speak straight to the soul. If you need something to relax, that's it.”'' —Sonny Zeppeli, Chapter 13

Sonny Zeppeli is the deuteragonist of Jojopolis and a main ally to Jordan Joan. He is a member of the Zeppeli family (probably being a descendant of one of Ceasar Zeppeli siblings since they were the only part of the Zeppeli family that was not extinct) and an police officer willing to help Jordan to stop his father's plan.

Appearance
Sonny is an italian man of above-average height with a semi-muscular build and short white hair. Sonny's maint outfit is composed of a shirt with his police badge pinned, a pair of black sunglasses, pants with a leather belt and leather boots.

Personality
Sonny is introduced as a determined, dedicated, loyal and kind police officer with a strong sense of morality and justice. Even when dramatically injured he doesn't bear any ill will towards his enemies (mostly because Sonny knows they are brainwashed) and, while Sonny could constantly use the full potential of Murder Most Foul, allowing him to easily destroy his opponent, he choose not to do so in order to avoid to hurt people, the only exception of this is his fight against Satch (and when he used Murder Most Foul at its full extent, he killed Satch in only a few seconds).

Sonny is also showed to dislike loud songs, liking more classical and relaxing songs, Sonny bear a great importance and a nostalgic, emotional attachment to Clair de Lune, being a song that his mother would sing to him while he was a kid. Even at Vietnam, Sonny would sing to himself this song, which was one of the few things allowing him to stay mentally sane.

Stand
Sonny's Stand, Murder Most Foul, is a slow but extremely powerful Stand, with the deadly ability to destroy living cells upon touching them.

Hamon
Sonny has been shown to know basic Hamon, but because of his lack of training he is rarely seen using it. Sonny is seemingly unable to perform more complex techniques than infusing his punches, kicks and projectiles with it but can at least combine it with his Stand.

Personal Skills
Tactical Thinking: While at the beginning of the story Sonny is hardly able to use Murder Most Foul in strategic ways (mostly because he never bothered to learn more about it before), he quickly learns and become a skilled stand user and a fairly brilliant tactician, being able to improvise in a lot of situations and deducing important facts about his opponent's abilities and weaknesses from short observations, his combat against Satch perfectly demonstrate this progress.
