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 insects' nest whom he commands to win his fights, and doesn't hesitate to try to murder competitors during the race.
Chollas carry seeds in their needles, so when an animal or something gets near them, the needles pop off from the plant as a response to the vibrations in the air. Normally one would have to be close to chollas to launch their needles, but by manipulating his insects, Mrs. Robinson can launch their needles at enemies from far.
Mrs. Robinson appears to be a competent horserider, having finished at the 18th place during the first stage of the Steel Ball Run 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
Mrs Robinson participates in the Steel Ball Run. In the first stage, he doesn't distinguish himself. At the start of the second stage, he is the first to follow Gyro Zeppeli and Johnny Joestar in the desert, aiming to assassinate them. Six hours into the second stage, Mrs. Robinson starts his attack and sends his flies trigger the chollas near Johnny and Gyro. They shoot their needles, piercing Gyro's ear and then attacking them from all sides. Still, Mrs. Robinson keeps his distance. He then makes it so a flurry of needles accurately cut Johnny's bridle and pierces his face, unhorsing him.
Gyro decides to confront Mrs. Robinson head-on. Gyro tries to throw his Steel Balls but needles hit his arm, making Gyro botch his throw and the Balls falls to the ground. Robinson reveals that he's breeding a swarm of flies inside of him to send them toward the chollas. However, Gyro also reveals that the vibrations of the Spin are still synched up to take out Robinson. The vibrations make some chollas explode near Robinson, who is shot down by a flurry of needles. Later, Mountain Tim sees Mrs Robinson lying on the ground but Robinson's ultimate fate is not revealed.
- “Take this! I will not allow anyone in this race to run ahead of me!”
- Mrs. Robinson shares similar traits with Donovan from Battle Tendency. Both are villains who have abilities that do not have anything to do with Stands, Ripple, or Spin, and both end up tied to a cactus and left to die in the desert.
