The Principal (To Love-Ru)

An unnamed Sainan Metropolitan High School principal from the school that Rito Yuki, Lala Satalin, Momo Bella, and Nana Astar Deviluke go to, is a minor yet recurring character of the harem manga series, To Love-Ru. He is introduced as an small overweight pervert who is not afraid to show his feelings to girls from school or somewhere else he finds attractive.

Why He Sucks

 * 1) There's no proper reason for him to exist since he's just your typical middle-aged stereotype who likes to sexually assault girls for fun, which makes Rito Yuki, the series' main male protagonist of the series look much like a full of jokes with no personality and developments.
 * 2) He is the harem equivalent of Herbert the Pervert, and a copy of Glenn Quagmire from Family Guy, Just like them, he feels more like a Family Guy character than a minor character from a harem anime.
 * 3) * And even then, both Herbert and Quagmire have memorable gags and punchlines, but both like to have sex, while the principal doesn't have any.
 * 4) His character design looks mediocre and unpleasant. The principal is a small dwarf-like middle-aged man who kinda looks like Mario from Super Mario Bros. with a Bendy-Esque hairstyle, and Peter Griffin with sunglasses from Family Guy.
 * 5) He may be middle-aged, but he is downright annoying and a pedophile. He keeps sexually assaulting female students for fun, steals their swimsuits and bikinis, and runs around in his underwear thinking any cute girl would come to him.
 * 6) * He goes across the line and has the audacity by attempting to assault Rito Yuki's sister Mikan, who's just 12-13 years old. Seriously, he could've gone to jail if he were to keep continuing to do to so!
 * 7) * He's also a masochist too, letting Nemesis sit on top of him in his underwear. Which is again, very unhealthy and creepy.
 * 8) He allows Lala Satalin Deviluke to be enrolled in school just because he simply thinks she's cute, that's it. And no, he didn't even have her to take the entrance exams, make her check around the school first, or at least inspect her, which gives further proof that he is a terrible principal.
 * 9) He is supposed to be taking his role as a principal very seriously and normally, but the way he acts, the sexual things he commits to his female students and gets away with it scot-free, makes the audience wonder: how is he still not fired from his job? Or how he got his job, or why didn't the school's director find out about his actions?
 * 10) Aside from being perverted, he doesn't really do much in the greater narrative and only serve as filler and comedy, but somehow gets a lot of screen-time in both manga and anime to the point his perverted gags start to become stale.
 * 11) He does not apologize to the girls for his perverted nature.
 * 12) *That makes Issei Hyodo from High School DxD, Jiraiya from Naruto and it's sequel Naruto Shippuden and Tomoki Sakurai from Heaven's Lost Property look like amateurs in comparison. At least Issei, Jiraiya, and Tomoki hide their attempts and each knows when to keep them in moderation.
 * 13) He barely has any comic relief attitude.

The Only 3 Redeeming Qualities

 * 1) His voice acting is good.
 * 2) He does sometimes leaves his students alone.
 * 3) He is not as antagonistic at all.
