The Stand appears as a fishing pole with the words 'BEACH BOY' written on top (omitted in the TV Anime). Its skull-shaped reel represents death.
Pesci summons Beach Boy from the center of his palm.

Despite its innocuous appearance, Beach Boy is a remarkably deadly Stand, both at long and short range.
Not only can it kill someone by shredding their heart with its intangible hook, but it is also nearly impossible to defend against. Pesci's masterful manipulation made Bucciarati deem it even more dangerous than Prosciutto's already formidable The Grateful Dead.
As a fishing rod, Beach Boy is not really suited for power, but its deadly sharp hook means Pesci can use it as a dangerous whip. The line can also be used to break someone's neck or choke them.
Hook and Line
Beach Boy's signature ability is to phase its line and hook through any object, including walls or flesh.
Beach Boy can phase through anything and hook people
Pesci skillfully uses his fishing rod to search for a target through obstacles and, like a fisherman, ensnares them when his hook makes contact. He is then free to reel in his catch or even tear through the whole body by wildly moving the hook, but as an assassin prefers to phase the hook through his catch's body in order to reach a vital organ and cut it from the inside for a sure-fire kill.
Beach Boy's pulling strength is only as strong as Pesci's own arm strength, but the catch will tire themselves trying to pull on the extremely elastic line.
Should Pesci drop Beach Boy, its abilities will be canceled and the hook and line will disappear.
By hiding the hook inside a chosen object, Pesci can use Beach Boy to bait and catch people by surprise.
Extreme Line Sensitivity
Beach Boy's line is extremely sensitive and transmits information to the handle of the rod for Pesci to see.
Beach Boy's hook and line can sense lifeforms, and are accurate enough to tell Pesci the number of people inside a given room and transmit the vibration of a heartbeat. Furthermore, by analyzing the vibrations and strength of the pull on the line, Pesci can accurately guess which body part he is hooking, the catch's weight, their position and their actions to the centimeter.
The string reflects damage at the catch
Beach Boy's string cannot be destroyed by any usual means, as any damage inflicted to the string will instead affect the one hooked on the string. It is thus impossible to destroy the string once it is hooked into an object or person. This property is a derivation of the line's intangibility: although it will phase through any object, the shock of any attack is transmitted into the catch's body. If the line is attacked by a Stand, the effects of the attacking Stand's ability is will be applied to the hooked victim instead.
