Boingo

Boingo is a minor, fictional characters appearing in the Japanese manga JoJo's Bizarre Adventure, by Hirohiko Araki. He's portrayed as an enemy of the protagonist.

Characters
Boingo and his brother, Oingo, are named after the group Oingo Boingo. Oingo is the (often overconfident) elder brother and the user of the Stand Khnum, which allows him to change his face at will. Boingo, the introverted younger brother, is the user of Thoth, a Stand that takes the form of a fortune-telling comic book.

Oingo attempted to kill Jotaro Kujo 2 times, first by poisoning Jotaro's tea then by making him eat a bomb that looked tasted like an orange but Polnareff threw the bomb out of the car in the direction of Oingo and it went off.

After Oingo's defeat, Boingo teams up with Hol Horse to avenge his brother (albeit only after Hol Horse had to resort to kidnapping Boingo). Hol Horse's intricate shot guided by Boingo through series of tubes was foiled because Hol Horse's watch was off couple of minutes when directed to fire at a certain time.
