I have several depending on what the setting permits. I'll break them down by setting for the characters most of these characters are set to certain varying species, but many can be defaulted to human(if not I'll state in descriptions:
Lysander/Lysippe VanGlef - Twin Nobles that adventure for stories to tell and impressive deeds to spread. The main goal for them in exploring is to become more renown and spread the word of their father's fief as a place of excitement, comfort and community. Though Lysander is marked as the heir to the region, Lysippe is seen as the more viable candidate, but due to the way the laws are set in their region females cannot hold titles for themselves. Originally a pair of rat-folk, but easily defaulted to human.
Aegus Minstral: A holy man, who effectively is an over-righteous zealot. He sees everyone as a sinner, though shows compassion for those that wish for repentance, mainly because he sees himself in such a poor light that he attempts to redeem his own perceived sins by carrying a heavy iron cross on his back. He is extremely religious and from a region that has little scientific knowledge, most boons granted by blind faith. Human.
Jinar Dei'Ro: An elven bard. He travels the lands, exploring with great curiosity and inscribing his treks in song, prose and other various acts. He's a light-hearted character with a lucky-streak, seeming to get out of bad situations not even by his own skills. His main instrument is a harp, but he has skills in other string instruments.
Karakt: A barbarian from a completely uncivilized hunting/gathering society. He is from a tribe of people that is constantly in war over scarce resources in the area that his people live. He ended up leaving his people after most of it was destroyed in a mass battle of various tribes, and is trying to either build a new tribe, or find a new world he can live in. Originally intended as a Lizardman, Karakt can be built up as a nordic-sort of human.
Alyssa Yuval: A woman who was stolen from her original parents and raised in a society that worships dragons as gods. She is a complete devout follower of the Great Reds, and has gone through ritualistic changes of her body as well as gathered iconic armor reminiscent of the idols of her worship. She is violent, brash, greedy and intent on finding a Great One to become her patron. She is a human.
Virgil Gemirio: A complete ditz of a man, but an amazingly compotent gun-fighter. Though he specializes in revolvers, he can handle a rifle as well. He is seen as a bit of a vigilante and, because he acts before he thinks, he has been on the WRONG side of the law and has some men that chase him on occasion, so he constantly moves. Though his heart is in the right place, he doesn't get all the facts before he jumps into some kind of trouble. Originally a catfolk, can easily be shifted to a human.
Orpha: A young thief, she is a bit of a pack-rat and an avid tinkerer. She was left to her own devices, raised by a group of kids in an abandoned town, and later went off on her own after there became an increased amount of raiders. She got seperated from her 'family' and just wanders alone, for now. She gets by though devious and conning tactics. Originally a ratfolk, but can be adapted to a human.
Volker: A very old man who mainly fritters his life in research. He mainly explores archaeological digs for interesting things and develops devices for the sake of being able to say he did it. He is, basically, throwing the adventures as a way to get something off his bucket list, thinking he is getting up in years and if he'd going out, may as well be something dramatic! Human.
Pauline Dier: A woman that was brought up in a bit of a rough neighborhood, where education was low, gangs were prevalent, and those that got to be older than twenty four were either hardened criminals or astronomically lucky. Pauline was the former, who had survived through dirty dealings and criminal cybernetic enhancement. She was involved in several gang wars and even snitched out a few people to shady corporations for an easier life. She had since grown to a kind of mercenary for money, using her contacts, wits and cybernetics to further herself in a new lifestyle. Human with cybernetic enhancements(Obviously). (Originally was a Shadowrun character)
James Darlington: An old man who had come from humble beginnings and made a big name for himself. He left his family and became a man in the (space) navy, eventually becoming an admiral through several sorties. When he managed to retire with honors, he developed his own computer-tech company that was successful. He has been the target of several corporate sabotage attempts and some slander, but he has managed to keep himself safe. After he passed his company to his son he started to get the idea of travelling, and exploring as space is vast, as is his fortune, and one of those seems endless. Human. (Originally a Traveler character)
Iris D'Argon: A woman who has been down on her luck since her youth and eventually came to benefit with a (adoptive) father that seemed to love her and want to pass down his knowledge to her. Eventually, though, the man found himself under attack for his brilliant technology, causing the woman to get injured. She had to have, basically, half her body rebuilt, and her father decided, for his safety, and hers, they would need to make a deal with a questionable organization. This turned to be a terror cell and in a raid against it her father was jailed and she was imprisoned as a terrorist. She eventually escaped and, using her father's old technology and her own developmental genius became a bit of an anti-government 'villain'. She's over-the-top and has an odd amount of fun causing destruction. Human, cybernetically enhanced.
I have PLENTY more, and even some of these may have shifting roles and drop in/drop out, depending on the setting, and what we achieve. Could be NPCs, or could be characters I play over time. I want to keep the world and characters fluid, where is someone gets bored with a character can say 'eh, let them go and stay in[city] and I'll play [new character] instead!
