Iggy Koopa (known as
Hop Koopa in the cartoons) is one of the
Koopalings, a clan of seven siblings that act as leaders of the
Koopa Troop under
Bowser (
originally considered his children). Iggy is depicted as a crazed, mechanical genius and childish in personality when together with
Lemmy Koopa. His two main outstanding physical characteristics are his glasses and light green hair (originally pink, light blue, and yellow). In later appearances, he is shown to be the thinnest of the Koopalings. Iggy is named after
Iggy Pop, a famous American punk rock singer and leader of the proto-punk band
The Stooges.
