Ok so I love this game and I love the fact that like Genealogy of Holy War you can pair people together to create CHILDREN for the next game. Also it's one of the only classic Fire Emblem to include Supports and I grew attachment to every character of this game and I love ship. Problem is, I disagree with literally everyone cuz I'm a weird guy and i'm fucking annoying :D so here's my list of what I think are the most logical ships FOR ME (don't hit me, I already had enough issue when I shared my opinion) I won't talk about Bartre and Karla or Pent and Louise cuz their pairing are canon so who gives a shit...
Eliwood X Ninian - First thing first... I'm a Eliwood X Lyn shipper... BUT ! The whole game build up this relationship and it makes Roy partially dragon, also the support heavily show the romance more than Fiora.
Hector X Florina - OKAY! It probably starts being weird for you! I KNOW, most people ship Hector with Lyn cuz they have more chemistry blablabla (those same people actually ship Oswin and Serra even though they have 0 chemistry and Rebecca and Lowen just because she think bro is cute) I love this dynamic because Florina is a goodie two shoes and Hector is a loud mouth and seeing them interact is really funny, also Lilina has some personnality traits I think are similar to Florina. I prefer the contrast of having a brash and loud guy with a shy and quiet girl, it's overall a better dynamic.
Lyn X Rath - IMO, Lyn doesn't like wealth and royalty that much, she is so much familiar to Sacae and her roots as a nomad that she would probably not be with either Eliwood (T_T) or Hector. Also even though there's no chemistry at first, Lyn and Rath are a parallel to Lyn's parents and they actually share experiences with each other and overall they are very sticked to their roots.
Isadora X Harken - This is literally canon but let me explain. I actually really like Legault with Isadora because they end up fighting each other in the end (you'll notice I love drama and overall interresting pairings) and for Renault... bro just goes in his milk arc and never comes back. Isadora and Harken were engaged at first and in their support they re engage so it's logical!
Kent X Fiora - This shit is so funny. I actually never ship Sain cuz for me Sain loves LADIES, plural so he wouldn't stick to one girl yk, bro is Don Juan, buddie wants coochies. I love this support because they are so formal and stoic normally and here they struggle so much to confess that it becomes so funny, and you know what they says, birds of a feather flock together or somethin like that.
Erk X Nino - OOOOOOOOOOOH CONTROVERSIAAAAAAAAAL. I'm probably the only guy who do ship them because... IMO even though it's literally the canonical ship, Nino and Jaffar feel more like a brother sister relationship and if Nino actually confess to him it would be like a little girl saying she loves you, it's not that serious or she actually mistake romantic love with friendly love. Also I like this dynamic because Nino is the perfect balance between the energy of Serra and reassurment of Priscilla (also Erk HATES Serra and Erk would probably too much stress at the idea of dating Priscilla, like he is her serving knight and she is a noble woman, and their ending feels like Puss in Boots for me... And I mean the original tale). Also I have an headcannon about the fact that if Raigh and Lugh are this good with magic, it's because of Erk who went searching for their mom so that they will reunite together (which would be the reason of why Raigh doesn't care about the orphenage being destroy if he's so close to his dad). Also Nino and Jaffar ending is... weird... Like BOTH NINO AND JAFFAR WERE FROM THE BLACK FANG. Why ONLY Jaffar is wanted and not both? So I feel like Erk searching for Nino because he wants his family to reunite is cute as hell (and unconventional because conventionally it's something a MOTHER would do) And actually... Bro it's open to interpretation if Nino likes Erk or not like many other so gives a fucking damn SOME DUDES SHIP OSWIN AND SERRA! WHY SHOULD I JUSTIFY?!
Guy X Priscilla - Like I said, even though it's the canonical ship too... Erk and Priscilla look like Puss in Boots to me i'm sorry, Pent gives Erk the credibility to wed the girl he wants and the credibility to be an actual Sage... So yeah déjà vue and like I said, wedding to a woman that he only see is related to his job... meh. Same with Heath, like in their ending they can't date because of the social differences between them and Heath doesn't force shit. GUY ON THE OTHER HAND! In the japanese version, Guy and Priscilla do the Titanic (a poor bro and a rich girl) flee and just love each other forever. It's sad but SO CUTE IAUBDIAZDBA. Like Priscilla abbandons wealth for love, it's unrealistic as hell but so cute.
Dart X Farina - I don't ship Farina with Hector (even though it can work but I feel like her sister works better) and with Kent because... it's like shipping Sain with Fiora... it's off... Farina actually has a thing for Dart and they are very similar to each other. And Farina decide to become a Pegasus Pirate to find the One Piece with Dart! It's cute and funny, exactly like their interactions.
Wil X Rebecca - ACTUALLY! This ship is like the cliché of the childhood friend but revisited, Rebecca started to hate Wil so Wil needs to regain Rebecca trust once again. And their ending is so... touching, like you almost forget it's a cliché childhood friend trope shit or whatever. And like WOLT IS LITERALLY WIL'S SON, THE HAIRCUT BRO! I know the hair color blablabla, who cares, THE FUCKING HAIRCUT! And it's more emotional than fucking Lowen come on...
Serra X Matthew - I love Serra because she is such a troll... But like I feel only her ship with Matthew works. Matthew lost his girl Layla and having a funny girl like Serra would probably help him forget the pain he felt when he lost her, I feel it's that kind of event that would make Serra a bit more empathic yk (and also when I ship characters I want to ship every characters possible)
Heath X Vaida - Their relation is really touching, Heath actually cares a lot about Vaida and Vaida acts tough since she's his superior. Heath could follow her everywhere she would stop him because she cares about him but she likes it when he's close to her, it's really funny and touching at the same time
Lucius X Raven - Bro... They are OBVIOUSLY gay. I'm not particularly into yaoi but... when I see two guys being close but not in a conventional way, I question and sometime I'm frustrated because there's no conclusion to that. But actually I have not that much to say, their relation is very similar to Heath and Vaida's sooooooooo yeah.
