Die for Our Ship/Sailor Moon




 * Mamoru Chiba/Tuxedo Kamen/Prince Endymion of Sailor Moon is definitely Relena's Spear Counterpart in regards to this. The guy is consistently portrayed throughout every part of the Sailor Moon franchise as Usagi's love interest, but the final series, Sailor Stars, introduced Seiya Kou as a surrogate love interest while Mamoru was absent and fans, seeing a het-ish alternative to Mamoru ("ish" because Seiya is a Gender Bender in the anime and a Sweet Polly Oliver in the manga), proceeded to take this opportunity to express their anger at Mamoru. Said anger stems mostly from a plot arc in the R season, where Mamoru broke up with Usagi after receiving disturbing dreams that their relationship would lead to The End of the World as We Know It. It really didn't help that the whole arc reeked of Idiot Plot in general and the entire situation came off as very contrived and melodramatic. But what people tend to forget though is that after that issue was finally resolved, Usagi did forgive Mamoru and he generally went back to being a serious and overall devoted and well-meaning boyfriend. But Never Live It Down is in effect here, as some Seiya/Usagi shippers will practically bend over backwards to color Mamoru up as this heartless asshole who hates her.
 * Poor, poor little Usagi is only stuck with that jerk Mamoru because she wants to have their future daughter. If she had a choice, she would be with Seiya. Never mind the fact Usagi and Mamoru loved each other before finding out they had a child together, Usagi was mostly oblivious to Seiya's feelings and saw her as a good friend, and it was explicitly stated in canon that Seiya's love for Usagi was unrequited (something that Seiya herself very gracefully and maturely accepted). No, that's not important. At all.
 * There's a Squicky subgroup that claims that Mamoru is in love with his own future daughter. Anime Usagi is shown to be so childishly jealous when Mamoru pays attention to Chibi-Usa that she even asks him in the Super S movie which one he loves more. Mamoru is understandably flabbergasted and gives no response, which sets up a Chekhov's Gun when Usagi is later trapped in an illusion with a fake Mamoru. Some of Mamoru's detractors will use this as evidence that he loves his daughter more than his girlfriend/future wife. It does not help that Chibi-Usa is quite clingy to him as well, and even refers to her father as her boyfriend. Still, this subgroup seems to be unaware of the time in R when the Black Moon clan tries to brainwash Usagi into joining them by attempting to make her think that Mamoru was in love with Black Lady, Chibi-Usa's magically aged up and brainwashed alter ego... but Usagi breaks through it and says this won't happen ever. Note that in the manga, Usagi's jealousy of Mamoru's attention to Chibi-Usa was actually addressed directly when Usagi confessed it to him - leading to Their First Time. Needless to say, Mamoru was a bit more direct about his feelings in the manga.
 * This also happens in reverse. Some Mamoru/Usagi fans don't take kindly to people splitting up the "Ultimate OTP" of the fandom. As a result, Seiya also gets a lot of hatefics where she's treated as if she deliberately tried to ruin Usagi's relationship to steal her from Mamoru, even though in canon, she respected Usagi's prior commitments, and in the anime, mistakenly thought that Mamoru had dumped Usagi without telling her. Even Mamoru trusted her and Usagi and was on pretty friendly terms with Seiya when they finally met. Both versions of Seiya (the Gender Bender from the anime and the Sweet Polly Oliver from the manga) took heat from the rabid shippers; the first more than the second, yeah, but still.
 * And then there are the Mary Sue fics that bash Usagi to have Mamoru get it on with the Sue. Or the crossovers that bash not only Mamoru, but also all of the Senshi (specially Rei, who briefly dated Mamoru in the anime but gave him up willingly) so Usagi will ditch the team and get together with Ranma Saotome, Farfarello, Heero Yuy, or Trunks. Or the Usagi/Rei Yuri fics that sound very similar to the Seiya/Usagi ones that make Mamoru a Jerkass...
 * All you have to do to split up Usagi and Mamoru is to make Mamoru a Jerkass. One Usagi/Haruka fic, without irony, condemned Mamoru for being a possessive, unloving jerk who was torturing Usagi's emotions and driving her into Haruka's virtuous arms. Meanwhile, it seemed approving of Haruka's romance with Usagi while ignoring her live-in lover, Michiru, who suffers extreme Chickification and is okay with Haruka cheating on her (!). The story ended with Usagi and Mamoru together after Mamoru was harshly scolded for his evil ways and Haruka nobly giving up Usagi and still getting to walk home with an ever-loving Michiru.
 * Rei Hino was demonized quite a bit by rabid Usagi/Mamoru fans for her crush on Mamoru. They painted her as a screaming, frothing homewrecker who wanted to kill Usagi and steal Mamoru all for herself. Never mind that in anime canon, Rei immediately stepped out of the way once she realized Usagi and Mamoru were meant to be, that she was the most protective of Usagi among the Senshi, that Usagi trusted her the most out of anyone in the Senshi, that she was somewhat paired up with Yuuichiro, and that Rei was the most affected in the Stars anime when she learned that.
 * Don't forget the Super S episode in which Mamoru had to spend the night at Hikawa since his apartment was in repairs. You'd swear it's a Take That to the Rei-bashing-from-Usagi/Mamoru-rabidshippers as Usagi got comically jealous of Rei and recalled how she used to chase after him, only for a squicked Rei to go all "What the HELL are you smoking?!"
 * It was once popular, during the English dub's heyday, to portray Haruka as a Psycho Lesbian who either perverted or abused Michiru, all to ensure that a Relationship Gary Stu could enter the picture and rescue her from the sin of homosexuality. A subversion occurred on a once-infamous website that posited the reverse - that Haruka was a shy, gentle heterosexual woman and Michiru forced her to be a manly lesbian. These days, now that Ho Yay is far more popular, they're one of the series' most popular pairings.
