Mrs. Robinson is a well-built yet heavily androgynous mexican man who has long flowing hair and prominently wears a string of eyeballs.
According to Mrs. Robinson, he had at some point lived in a small village in the desert where he had lost some type of duel. As the loser of the duel, he was purposely chained to a cactus with the intent that he would die a slow and painful death. Having somehow managed to survive, (Although he says it was because of a curse that he was brought back from the dead), he became a slave to revenge. He continued to exist in the village, but in order to separate himself from the others, he began raising insects within his own body. Aside from this, nothing else is known about Mrs. Robinson.

He was outsmarted by Gyro and quickly dispatched. It is unknown as to the nature of Mrs. Robinson's powers.
