L. A. Boom Boom

L. A. Boom Boom (Ｌ.Ａ. ブンブーン) is a minor antagonist featured in Steel Ball Run.

L.A. is the youngest member of the Boom Boom Family along with his father Benjamin and his older brother Andre. Participating in the Steel Ball Run, he attacks Johnny Joestar and Gyro Zeppeli to eliminate competitors.

Appearance/Personality
L. A. seems to be a nearly twenty years old boy, with long hair, but no particular physical character.

His personality is really interesting indeed: he doesn't seem to be perfectly sane, probably because of the loss of his mother and the strong presences of the other two members of the family. He is shown crying in numerous instances, and generally acts like a child, calling his father 'daddy' and is constantly in need of his help due to his lack of confidence. His humor changes from happy to sad, from scared to angry very quickly.

Compared to the other members of his family, he seems to be of lower intelligence, but has sudden moments of keen observation which are only met with his family's scorn. For this, Benjamin calls him 'the family's smartass'.

Stand
The Boom Boom family's Stand, Tomb of the Boom, grants every member with the ability to manipulate iron in different ways. In L. A.'s case, it allows him to manipulate iron sand to immobilize his victims. He is capable of killing a person by extracting iron-rich blood from someone and kill them. L. A.'s Stand manifestation also seems to be the most combat-oriented of the family.

Synopsis
After his brother Andre tricks Gyro and Johnny and manages to transform the first into a human magnet, Benjamin and L. A. attack them unsuccessfully. However, Benjamin quickly elaborate a new strategy, turning Johnny and Mountain Tim into magnets too. Leaving Andre alone, L.A. and Benjamin trail Tim and the protagonists, but before the magnetism can kill all three, the cow-boy uses his Oh! Lonesome Me to stop himself from colliding with Gyroa and Johnny.

L.A. and Benjamin are forced to approach the trio. L.A. uses his Stand to immobilize Gyro and Johnny and Benjamin cuts Oh! Lonesome Me, forcing the three to collide and almost killing them.

However, Johnny awakens a Stand Power and cuts Benjamin in two, as well as severing one of L.A.'s foot. With his father lying in his arms, L. A. reveals that their actual goal was killing Gyro in order to earn his bounty. Even if all members of the Boom Boom family are doomed, L. A. says that Gyro won't see the end of the race, because other people will try to be rid of him.

After their father's death, it is unknown what happens to him and his brother.
