Iggy is one of the two highly incompetent cousins of President Koopa who is sent to the human realm to kidnap Princess Daisy, the other being Spike. The two initially failed their mission, kidnapping several women before being able to seize the right one. They were later ordered to capture the fugitive Mario brothers.
As Koopa was eventually fed up with the duo's stupidity, he forcibly put them in the Devo Chamber, but instead of devolving them, he had them evolved in order to increase their intelligence. This eventually backfired, as the now-intelligent Iggy and Spike realized that their cousin Koopa was an oppressing dictator and changed sides, becoming allies of the Marios and Princess Daisy.
