Andre Boom Boom (Big Brother)
Benjamin Boom Boom (Father)

This is a minor character featured in Steel Ball Run.
L.A. is the youngest member of the Boom Boom Family, along with Benjamin and his older brother, Andre. While participating in the Steel Ball Run, they attack Johnny Joestar and Gyro Zeppeli to collect the reward. L.A. is a young man with long, flowing hair and dark eyes. He wears the same dotted suit as his family, with a target on the chest and goggles.

L.A. has poor academic skills, such as an inability to do basic math. Along with being prone to uncontrollable emotional outbursts, he is also extremely naive, believing his mother was a stork because Andre told him so. He is generally emotionally dependent on his father and brother. Likewise, he looks up to his brother like a small child. Despite constant verbal abuse from both, L.A. doesn't mind their insults and becomes attached to them, becoming furious when his father dies.

Compared to other members of his family, he appears to have a lower intellect, but he has very keen observation skills that are met only with disdain from his family. For this, Benjamin calls him "the smart one of the family."

The Boom Boom family's Stand, Tomb of the Boom, grants each member the ability to manipulate iron in various ways. In L.A.'s case, this allows him to manipulate iron sand to immobilize his victims. He is capable of killing a person by extracting their iron-rich blood. L.A.'s Stand also appears to be the most combat-ready of the family's Stands.
