[[caption-width:320:The moment where "fandom feminists" and {{Yaoi Fangirl}}s came together and started gunning for a little girl's death.]]

As a sports series brimming with HoYay / FoeYay for the male characters, ''Manga/ThePrinceOfTennis'' is also a breeding ground for [[DieForOurShip shipping wars]]. Not only of the [[HetIsEw "women are horrible and so are het pairings"]] type, mind you.

* In the fandom, [[ShrinkingViolet Sakuno]] and {{T|sundere}}omoka are heavily bashed by {{yaoi fan|girl}}s since they both have crushes on [[TroubledButCute Ryoma Echizen]], the male lead who is [[YaoiGuys very slashable]] in fandom despite being just 12-to-13 years old. Their biggest sins? [[HetIsEw Being females.]]
* In the case of DatingSim girls, [[CuteClumsyGirl Tsugumi Obinata]] from ''Sanroku no Mystic'' gets the biggest share of bashing because of her quiet, sweet and shy personality that makes her an {{Expy}} of the already maligned Sakuno. The comparisons between her and the more outspoken [[{{Shorttank}} Ayaka]] [[PluckyGirl Tsujimoto]] from ''Umibe no Secret'' always give her the shortest end of the stick, and she's deemed as [[RealWomenDontWearDresses weaker and stupider]]... in spite of the fact that she and Ayaka ''[[TomboyAndGirlyGirl are best friends]]'' in-story.
** Also, Shizuka Hirose from the ''Gakuensai no Oujisama'' game. Completely loathed and accused of being a cockblocking Mary Sue... even when the games are obviously not canon (and neither are ''Umibe'' and ''Sanroku'') ''and you can choose who to pair her with''!
*** The trope is also sorta invoked in-story in ''Gakuensai''. If [[TheAce Keigo]] [[TheRival Atobe]] is the chosen love interest, Shizuka [[StockShoujoBullyingTactics will be attacked, threatened and bullied]] [[YokoOhNo by Atobe's jealous fangirls for daring to be close to him]]. [[spoiler: So much that, if Atobe learns about this, not only he will call Shizuka out for '''not''' telling him about the bullying she has gone through, but he will have to ''protect and hide her from his own fans'' at some point.]]
* [[GeniusBruiser Yanagi Renji]] has been bashed by Inui/Kaidoh fans ever since his and Inui's backstory was brought up, because he used to be Inui's best friend and partner before Inui met Kaidoh [[spoiler: and [[NeverGotToSayGoodbye left him without saying anything]] when his family moved]]. That's seen as Renji being an horrible and heartless person who hates Inui and wants him to suffer, so his ruthless in-courts behavior (which is a trademark [[KnightTemplar of the Rikkaidai team]] ''[[KnightTemplar as a whole]]'') is "proof" of his cruelty, in spite of it being hinted that [[spoiler: he preferred to put a JerkassFacade and [[ItsNotYouItsMe remove himself of the picture]] to not hinder Inui's development as a player]].
** This happens even when, in the Finals OAV depicting the Rikkai vs Seigaku second matches, Renji goes {{Kuudere}} and ''begs'' Inui to [[spoiler: forfeit the match when he gets injured by Kirihara during their doubles match in the finals, thus proving his bashers wrong]]. The fact that he's acting emotional ''in front of [[spoiler: Yukimura]] himself'' should clue these fans in, but some still insist Renji is ''[[ManipulativeBastard faking]]'' his concern for Inui.
* Inui/Kaidoh fans have also been known to bash Momoshiro, who (it is implied) later [[spoiler: became Kaidoh's vice-captain after Inui graduated]], by flanderizing his BigEater ''and'' FunPersonified character traits to make him an absolute idiot who stuffs his mouth, causes trouble for Kaidoh, and barely does anything else.
* We also have the bad treatment [[IllBoy Seiichi Yukimura]] receives from rabid Atobe/Sanada fans due to Sanada's obsessive (and very slashy) devotion to Yukimura, which they see Yukimura [[ManipulativeBastard being domineering and possessive of Sanada]] to not give a chance to their ultra-prettified PossessionSue version of Atobe. And some particularly rabid Sanada/Yukimura fans retaliate by bashing ''Atobe'' for daring to get in the way of their super-perfect and super-beautiful OTP.
* Or how some [[IncestIsRelative Fujicest]] fans demonize and bash Yuuta's {{s|mugSnake}}cheming and [[AlwaysCamp flamboyant]] [[TheStrategist manager]], Hajime Mizuki. Granted, Mizuki [[KickTheDog wasn't introduced as the most likable person]], but not only [[CantGetAwayWithNuthin * did* he pay the price for it]], he's not as heartless as rabid Fujicest fans claim he is.
* Or the portrayals of [[BigBrotherMentor Tezuka]] and [[ForgottenChildhoodFriend Saeki]] in fics and doujinshii depicting a Tezuka/Fuji/Saeki love triangle, depending on who the [[YaoiFangirl fan writer or doujinshi author]] likes with Fuji the best. Saeki often takes the brunt of it, sadly.
** Take this paragraph, replace Saeki with [[GentleGiant Kawamura]], and there you go. Tezuka/Fuji and Taka/Fuji fans were okay at first with each other, but the mutual bashing and '''specially''' passive-aggressiveness have escalated with time. And nope, no side is innocent in this: Tezuka/Fuji fans are often rather butthurt for Kawamura's share of Fuji ShipTease, but the Taka/Fuji fans are prone to be ''incredibly'' whiny and victimized at the mere mention of Tezuka and [=TezuFuji=].
* An doesn't have it THAT bad, but she still gets pot shots for "stringing Kamio along" and "playing with his feelings" because she's friendly to him but doesn't seem to acknowledge his crush on her. Which brings up rather creepy UnfortunateImplications about how women should "owe" men love because they show open interest on them. (Or for that matter, anyone owing anybody else love in such circumstances.)
* The hate against almost any female characters in this fandom is (and hopefully, was) so ridiculously strong that ''even Shioin Higaki from the live-action movie got a share of it''. A cute mute girl who [[SuspiciouslySimilarSubstitute replaces Sakuno]], plays the flute, is the little sister of Egate Higaki (the guy who replaces Hiyoshi in-story) and forms an OddFriendship with Ryoma, Shioin immediately got petty "[[MarySue Maaaary Suuuuuue]]" cat calls from the yaoi-crazy fangirls; it died almost immediately off since this was her only intervention in the POT canon, but it still proves how almost any girl in this fandom '''will''' be loathed by the fans.
* Also add [[PrincelyYoungMan Atobe]] to the list, as he is the main target of the Tezuka/Fuji and the Sanada/Yukimura shippers, among other pairings. Atobe is either atacked by Fuji fans in retalliation for severly injuring Tezuka's arm and separating them, or by Yukimura fans because he was "meddling with his relationship with Sanada while he was at the hospital".
