L. A. Boom Boom

A young man with long, loose hair and eyes lost in shadow, L. A. dresses in the same target-marked, polka-dotted suit as his relatives and keeps a pair of goggles pushed up on his head.

L. A. struggles with the basics, unable to handle simple arithmetic, and swings into sudden emotional fits. His naivety runs deep enough that he once believed a stork had been his mother, purely because Andre had said so.

He leans heavily on his father and brother and looks up to Andre the way a small child would, shrugging off their constant insults and turning furious when his father is killed. Though his family treats him as the dimmest of the bunch, he lets slip flashes of sharp insight that only earn their mockery, prompting Benjamin to brand him the family's smartass.

The Boom Booms picked up their shared Stand, Tomb of the Boom, while scouting the Devil's Palm for mines, and L. A.'s version bends iron sand to pin down his targets and can kill by drawing the iron out of a victim's blood. During the race's opening leg the family murders three racers, drawing the notice of bounty hunter Mountain Tim, and they soon set their sights on Gyro for the price on his head.

Andre turns Gyro into a living magnet, and when the first ambush fails Benjamin extends the magnetism to Johnny and Tim, though Tim's Oh! Lonesome Me halts the deadly collision. L. A. immobilizes Gyro and Johnny while his father severs the rope holding them apart, nearly crushing all three together, until Johnny awakens Tusk, cuts Benjamin in half, and severs a foot from L. A.

Cradling his dying father, L. A. reveals the hunt was always about claiming Gyro's bounty and warns that others will keep Gyro from finishing the race. With Benjamin dead and Andre presumed lost to his wounds, L. A. is left with barely any water and out of the rescuers' view, dying of thirst soon after.
