I have 3 main characters and am one of those weird roleplay-y types.
Saefinn is an effeminate and recovering alcoholic of a pirate captain (under the Maelstrom's Black Sails). Born and raised Lominsan. Has a massive ego and tremendous luck, yet is stuck with a curse that the more he drinks the higher the chance he gets shot. For a time he did not realise there was that correlation until he learned to stop drinking. He's a learned character, was a runt so was never really all that strong and years of alcoholism dull the senses, so he's more likely to shoot himself if he got a hold of a gun (and has done exactly that, more than once). So he's acquired the self-given title of "Scholar Captain" as it was only his mind he trained and he is a very talented mage; intelligent, yet dumb. He can be a troll of a character at times, he's not very politically correct and puts himself into situations for saying the wrong thing and yet never seems to learn. But he enjoys pushing people's buttons, even if on more than one occasion he's almost lost a lung for it.
At times he can be obnoxious, like referring to the Sekisegumi as the "Sexy-sae-gumi". A Sekisegumi who was having a bad day arrested him for one such comment, it turned out the guy was having wife troubles and so Sae bonded with him, they talked it out and in the end the Sekisegumi felt a lot better. More recently, his first mate spiked his drink with a fantasia and I'm exploring his journey as a female Viera, it was only going to be a temporary gag, but...well, it has been an interesting thing to tackle, I'm doing it as tastefully as I can, whilst my character is more on the distasteful side in nature, it makes for an interesting balance.
X'hayu is Saefinn's partner (jokes about dating yourself ahoy), she was a Garlean defector who was a part of the Ala Mhigan occupation and carries a lot of guilt with her. She basically did a Cecil, took on the path of a Paladin to redeem herself, she saw Nanamo and her desire to help Ala Mhigan refugees and those who might attempt to usurp her, X'hayu ended up taking her pledge as a Sultansworn. She resigned from the role when Stormblood came about so she could help in the Ala Mhigan resistance, especially given her former Garlean background, she felt she has useful information to give as part of the resistance and since independence was achieved, I've had her trying to learn to adapt to a 'normal' lifestyle, where she's not in the military following orders and is struggling. How she ended up as Saefinn's partner I guess can be summed up as 'opposites attract', because for the longest time she hated him, but his good qualities ended up becoming more apparent and she found herself respecting him more.
Yesunova is my third, who is the character I have tied to my forum account. She's from the Azim Steppe, formerly of the Hotgo tribe, for those less familiar with the lore, the Hotgo tribe were massacred by the Dotharl and very few remain alive (and are the reason why the Dotharl numbers are low and are replenishing at the moment). The only two Hotgo we see in the game were a part of the Alexander plotline (Mide and Dayan) and the tribe's founders are said to have emerged from a metal giant, a boy and a girl, which ties really well with how the Alexander plot ends.
Yesunova only knows the stories passed down generations and is completely unaware of the connection between Alexander and her tribe, though I do have plans for her to learn about this. She's a huntress and performer who also can cook. She is probably the least broken of my characters, because she has a very level head. Whilst Saefinn has his alcoholism, X'hayu has her dark past in the Empire, Yesunova may have lost almost everybody she ever knew and loved, learned to come to terms with it, partly as it is not unusual in the steppe and because of the teachings passed down to her - as a result she is very 'zen', has a very friendly and warming nature about her and will often try to see the good in other people.
Initially I started her as a character to challenge my own writing because I've never written a character anything like her, but now that I've got inside her head and figured her out as a character I'm pretty proud of how she turned out and I enjoy roleplaying her.
I also have minor character's I use for Roleplay. But for some of my "dumber" plots I have some gag characters too. Admiral Eorzea (he's dead now, but basically Captain Planet as an eco-conscious mage), Cosmo Kayne (Admiral Eorzea's brother, basically Kanye West) and the Chucklef***s (the Chucklebrothers, who're a national treasure here in the UK).
