A. Phex Brothers

Aside from a single distinguishing trait, the two men are visually interchangeable. Their heads are cropped almost to the scalp, though the younger sibling keeps a trailing ponytail, and both display elaborate sideburn shapes alongside pierced ears. Their outfits echo soccer kit, patterned long sleeves worn with shorts, and their eyelids stay lowered so far that the pair often look asleep.

What sets the elder apart is his malformed right hand. That deformity visually nods to the Locacaca's equivalent-exchange principle, quietly signaling the agenda the two carry.

A guiding motif for the pair is the Japanese idea of A-un, the harmonious pairing of opposites, which frames them as two halves that complete one whole. Leadership falls to the older twin, who does the talking and at first seems to be the only one with a Stand; he also fronts their dealings, handling a pair of curious officers on his brother's behalf.

The younger man stays quiet by preference and only reveals his own power later, having kept it stashed inside a soccer-ball bag. He passes the time juggling that container with a footballer's flair, a habit that doubles as cover while they search for their target.

Born without names like other Rock Humans, the twins adopted human identities and eventually signed on as killers for the Locacaca Organization. In August 2011 they were ordered to eliminate Josefumi Kujo and Yoshikage Kira, but Josefumi overpowered both and sent them tumbling off a cliff. Redirected onto Karera Sakunami, they trailed her for roughly half a year.

Their paths crossed hers in Morioh while she traveled with Josuke. The elder wields Schott Key No.1, which relocates whatever his left hand touches to the stump of his right, letting him reassemble the material however suits him. His brother's Schott Key No.2 leaks a corrosive, blood-drawing gas from its container that the first Stand can ferry into an attack. Using this pairing, the elder doused Karera in siphoned gasoline and tried to set her alight, only for Josuke's Soft & Wet to intervene.

Judging Josuke the greater unknown, the two turned on him instead, whereupon Karera returned and burned them both. Their upper bodies calcified and crumbled into rubble.
