Mrs. Robinson (ミセス・ロビンスン Misesu Robinson) is a minor antagonist featured in Steel Ball Run.
Mrs. Robinson is a well-built yet heavily androgynous mexican man who has long flowing hair and prominently wears a string of eyeballs.
Parts of his body are hollowed out in order to breed insects inside, notably his left eye socket.
Mrs. Robinson is an unscrupulous competitor in the Steel Ball Run.
Influenced by his village's tradition, where a dispute can degenerate into a fight and the loser is tied into a cactus and left for dead, Mrs. Robinson is a cold-blooded and deranged killer. He has, in order to survive in his village, transformed his body into an insect's nest whom he commands to win his fights, and doesn't hesitate to try to murder competitors during the race.
According to Mrs. Robinson, he had at some point lived in a small village in the desert, where a dispute could degenerate into a fight to the death, and the loser was tied to a cactus then left for dead. It was believed in this village that the cacti cursed the loser and enslaved them to the revenge they would never get.
In order to always win such fights, Mrs. Robinson heavily modified his body, transforming it into an insect's nest and using the insects to his advantage.
Steel Ball Run
During the second stage, Mrs. Robinson was shown to quickly attack Johnny and Gyro, hoping to eliminate them. He used his insects to trigger chollas and steadily attack the duo without being suspected, but Gyro soon understood that he was their opponent. The Neapolitan used his Steel Balls to return the chollas against Mrs. Robinson, whom he overwhelmed with thorns and swiftly dispatched. His ultimate fate is unknown.
- Mrs. Robinson shares a similar fate with Donovan from Battle Tendency, both being chained to a cactus and left to die in the desert at some point.
