Well, like the title already says, what made you create your 'sona?
Concerning mine, this will probably shock and amaze you, but contrary to popular(?) belief,
Ken from Street Fighter wasn't my inspiration for Jaryl, even though you could say both look pretty similar to each other, what with the blond hair and the predominant red colors.
No, back then, I think 6 years ago, I wasn't even aware of Street Fighter. xD In reality, it was
The Legend of Zelda: Twilight Princess, which motivated me to start writing a story, since I was really fascinated by that game (after all, it's one of my favourite games of all time), and I wanted to try and write a story myself. But this isn't about the story, it's about Jaryl himself, and the game is guilty of that as well. You see, Link has the ability to
transform into a wolf in Twilight Princess, and since I really really like wolves, I wanted to include one as the main character too. Though I figured that I couldn't have my character also transform into a wolf, since that would just be considered a rip-off. I still wanted to set my story in a medieval world, with swords and all that (since I like games/comics/series/whatever set in medieval times. Also, the more magical they are, the better, as long as it's done well), which is why I made him more human-like, into an anthro-wolf, if you will.
Well, and even then, he looked kinda different back then, Jaryl was younger and was wearing blue and white instead of the red and black he wears now. He also didn't have the scar on his snout.
Personality-wise, he was also more of a "doing good stuff all the time"-kind of guy, since, well, I was quite naive back then ^^" Over the time, though, he gained his "calm, collected, a mercenary and very very deadly"-shtick, similar to Zero from the
Mega Man X and
Mega Man Zero-series, who also fights with a sword (a laser-sword, in his case), and tends to stay calm and professional. Also, I guess the recruitable Myrmidons/Swordmasters from the
Fire Emblem-series kind of inspired me here too, since they also tend to be the more serious and quiet guys you'll get in those games, next to being almost exclusively "hired guns" in the series, which Jaryl also grew to be.
So, long story short, Jaryl came to be thanks to a Nintendo-game, which you wouldn't be able to notice from just looking at him. Weird, I know. xD
