Iggy

"MWAHAHAHA!!! It's time to get our hands DIRTY!"

Lore
His past is unknown, but Iggy Koopa was one of the young Koopas that was adopted by Bowser along with other 6, after his family vanished from the face of Earth. Ever since, Bowser took care of the young Koopa as his son, and revealed his potential as a genius. But, he wasn't exactly a bright genius as it was thought to be. He was more lenient on a crazier side, as he was creating bizarre things that didn't seem to have no purpose, but Iggy was too determined to make them useful. Most of them managed to be useful in the end, while others blew right in his face, literally.

Years passed, and Iggy eventually became a great asset to Koopa Clan. He was mainly offering weird contraptions that surprisingly worked and his attractions were quite the buzzer. His days working on this stuff made him change his fashion as well: Making his hair sprouted and wearing mad scientist glasses. His appearance made everyone call him the "Cuckoo Wedge".

He eventually joined alongside his father with his siblings, following Bowser's schemes to the end. And Iggy usually came up with bizarre contraptions as always, to attempt defeating the heroes of Mushroom Kingdom. Despite his attempts, he doesn't succeed unfortunately. But he works hard and hopes that one day, his final creation will be successful.
