A. Phex Brothers
The A-un Twins are minor antagonists featured in Part VIII: JoJolion.
They appear to be hunting Karera Sakunami, presumably for her knowledge concerning the Rokakaka fruits.
Appearance
Besides the elder brother's crippled right hand both are identical in appearance and attire. Sporting nearly shaven heads with intricate sideburn designs and pierced ears, they wear long-sleeved decorated shirts and shorts which are reminiscent of typical footballer clothing.
Personality
As their name suggests, the pair share a duality described as harmonious with one another. Being based on the Japanese concept of 'A-un', which explains the connected nature of opposites and their seemingly contradictory similarities.
Aside from that the elder of the two brothers seems to be the one in charge, and so far the only one to speak. He is the one who communicates with the policemen in place of his brother and the one who displays a Stand power, although it is unknown if his brother also possesses one.
Abilities
Stand
The elder of the twins possesses an unnamed Stand power which allows him to transport objects from his left hand to the stump of his right hand; this takes the form of whatever his left touches disintegrating into dust only for it to reform where his right hand should be.
He has the ability to form objects around or inside of other things in the path of his right stump as he did with the officer and his handcuffs, and also he can suddenly disable his power and cause the two halves of whatever he was moving to re-attach, usually resulting in an awkward positioning such as in the case of the other officer's arm being displaced through the handcuffs.
The younger brother demonstrates versatile and dynamic control of his football common of experts, capable of moving it between his legs and head effortlessly and kicking it with enough force and power that it could be considered an attack of it's own.
Rock Physiology
While similar to a human's, their bodies can presumably change into rock. Because of this, they does not need to sleep or rest. They can mimic rocks to the point that it makes them indistinguishable from them.
Norisuke theorizes that Yotsuyu's physiology requires him to have at least a small amount of skin respiration and in the absence of such his body structure will begin to break down due to it becoming less structurally stable than an ordinary human's. This could be a trait shared by other Rock humans, including the A-un twins.
Synopsis
The pair are first observed performing tricks with a football in the streets of Morioh as Josuke and Karera walk on, to the amazement of the gathering crowd.
Later on they are again seen seated in a cafe where Karera steals their wallet and uses their credit card and her Stand power to obtain money she goes on to spend in a shopping spree. As the two walk away the twins can be seen questioned by a pair of policeman as to the strange nature of their ball and what one officer perceives to be a rock held in the hand of the older brother. When he demonstrates his Stand in subduing the policemen dialogue exchanged between the two brothers suggests that they have been hunting Karera and are surprised she has lasted this long.
Searching the streets for people who have come into contact with Sakunami, they eventually run into her and Josuke when the pair are nearing Kira's apartment, and the younger brother acts as a distraction while the other grabs Karera from behind and uses his Stand to transport the fuel in a car's tank all over her, proceeding to set her ablaze if not for the intervention of Josuke's Soft and Wet.
At the realization that Josuke appears to be a more pressing threat they decided to prioritize him as their target while allowing Karera to escape, more fixated on discovering the identity of the strange and powerful man who also has a ties to the Rokakaka fruits.
