Iggy Koopa (known as Hop Koopa in the cartoons) is a member of the Koopalings, a seven-member clan loyal to Bowser. Iggy and his siblings are very loyal to Bowser and were originally depicted as his children. This idea was usually omitted in games released after their debut in Super Mario Bros. 3, and Shigeru Miyamoto stated in a 2012 interview that Nintendo's current story was that they are not Bowser's children, leaving Bowser Jr. as his only offspring.Iggy is depicted as a crazed, mechanical genius. His two main outstanding physical characteristics are his glasses and green hair (originally pink, light blue, and yellow).
