Iggy Koopa (The Koopa Kids)

Iggy "Ignitor" Koopa is one of the villainous antagonists of the 2013-16 YouTube animated series The Koopa Kids.

Sadly enough, with this portrayal, Iggy was flanderized throught the whole series, but fortunately he would eventually revert to his former personality.

Why He Is (Intentionally?) NOT Fun
Note: These pointers apply only to his character as depicted in the cancelled YouTube series "The Koopa Kids".
 * 1) First and foremost, he went from being a vulgar, crazy but enjoyable, funny and overall a fan favorite to one of the most hated characters in the series due to his excessive sadist and malicious nature;
 * 2) Unlike other characters, who have humorous and spot-on impressions, his voice can grate on your nerves in no time, as he laughs histerically every two/three lines;
 * 3) His relationship with his older yet tinier brother Lemmy is one of the main reasons of why even the original creator of the series, Freezeflame22, hated the character:
 * 4) Although his hatred is justified due to Lemmy accidentally cutting his hair off, he did much worse things to him such as forcing him to do his chores, trying to dial his self-esteem back by yelling at him when he fails at doing them, and especially beating him up at school and breaking his bones, coming across as a mean popular boy, and attempting to kill him by throwing him off a cliff;
 * 5) To be fair, even before the hair incident, he treated Lemmy like garbage, constantly yelling at him and treating him like his butler;
 * 6) Hypocrisy: He finds him too hyperactive and annoying, however he is no better, as he shouts and, like Lemmy, spins around all the time;
 * 7) Unlike Ludwig and especially Roy, whose rivalry with respectively Bowser Jr. and Morton got slightly toned down as the series progressed, he never received enough character development to forget the past and treat Lemmy better, even when he tried to make up with him, including the time he saved his life.
 * 8) It's shown that he would eventually cower behind Roy and Ludwig, who are much stronger to him, everytime he does something wrong. This is evident everytime he beats up weak characters like Wendy, Bowser Jr. or Larry or characters who do not retaliate at all, like Lemmy, as he almost never does it alone;
 * 9) Informed attribute: He is often said to be the smartest Koopaling who comes up with useful inventions, yet he shows to be just as stupid and incompetent as other dumb characters like Bowser or Messenger.
 * 10) In "Airship Repairs", he took a job as a doctor, and he drank a bottle of soda in front of a patient, not knowing that it would be risky for the patient himself, causing him to pass away.
 * 11) Even his arch-nemesis Lemmy, who is often portrayed as the idiot comic-relief of the show, manages to shine thanks to his empathy and emotional intelligence which makes him more than just a character made for cheap laughs;
 * 12) He is a horrible pet owner, as he often abuses his pet Chompy with his torture experiments and he doesn't even feed him which is animal cruelty, as revealed in one episode in which he complained about Lemmy feeding Chompy with a piece of candy.
 * 13) He shows no empathy to anybody whatsoever, in "Bowser's Daughter", he and Ludwig laughed at Lemmy and Morton for missing her sister Wendy who could have been dead by the time the plane crashed. Morton reasonably asked what would have they done if it was Roy who fell off the plane and they didn't even answer, meaning they're also huge hypocrites who call out the others' issues and not theirs.
