This page explains in detail the interactions between the Balloon Fight series and the Mario series.
Balloon Fight Game & Watch[]
November 19, 1986
The boss of the Sky Pirates, featured exclusively in the Game & Watch remakes of Balloon Fight (both New Wide Screen and Crystal Screen) is called "Oiram Repus", which is actually "Super Mario" spelled backwards. The character itself has no resamblance or reference to Mario.
