Oingo

Oingo is a minor antagonist appearing in Part III: Stardust Crusaders.

Personality
Oingo is often overconfident due to the deadly ability of his stand to disguise himself combined with Boingo's stand ability to predict the future. This overconfidence backfires, however, when Oingo becomes the downfall of the prediction he trusted in.

Synopsis
Oingo attempted to kill Jotaro Kujo twice: first by poisoning Jotaro's tea, and next by trying to make him eat a bomb that looked like an orange. Jean Pierre Polnareff, however, threw the bomb out of the car in Oingo's direction, setting it off in Oingo's face and causing him to be defeated.

Trivia

 * Due to copyright laws, Oingo and Boingo were renamed Zenyatta and Mondatta respectively in the Viz translation, after The Police  album of the same name.
