Personality: Sothe is somewhat quiet and likes to keep to himself. He doesn't open up about a lot of things to a lot of people (except perhaps Micaiah), but he's not a bad person. In fact, he's rather kind. He cares about the "little people", so to speak. Sothe is very dedicated to his friends and companions and fights willingly by their side. He will go to great lengths to give his aid, though 'great lengths' are not often needed since he's so skilled at what he does. Because of where and how he grew up, he does, however, have the tendency to be suspicious of everyone he meets. When he was first found by Ike three years prior, he wasn't gung ho about being friends with the young commander. He was dedicated, however, to finding his 'lost friend' and became a valuable ally. Perhaps he's a bit overprotective when it comes to people he cares about, but people are really all that he has or is even able to hold attachment to. And while he does care and does respect several people (most notably Commander Ike), he doesn't really seem to be the type that makes friends and interacts with them on a personal level (as proven by Tormod's escapades to be his best friend ever). He is prone to disagreeing with Micaiah, his closest companion since childhood, quite often, though he shows that even through vast disagreement, he's still able to stand by her side and is willing to fight for her goals despite differing opinions. Sothe was forced to grow up far before he was supposed to, and so he seems to have a mature understanding of a cruel world, and wants to give it something of a chance.
He likes stealing things, being sneaky, and keeping his friends safe. He doesn't like oppressive rulers or dishonest people, and he's not extremely fond of nobles.
History:
This is a wiki page. :D (spoilers ahead) Strengths: Sothe is fast, agile, and light-footed, thanks to his years as a thief. He can pick locks and is very talented with daggers and knives (which he can both cut you with up close and personal, or throw from a fair distance away). He's also got a fair level of experience with acrobatics. He can use blades and do a backflip at the same time. Mentally, Sothe is reliable and open-minded.
Weaknesses: Not exactly the friendliest fellow. Not the meanest either, but you may find yourself with a lost cause if you intend to be his bff. In the Fire Emblem universe, the fact that he has no magical skills may be considered a weakness of sorts. His defense is somewhat poor (it's usually not needed since he's the one doing sneaky attacks), and really, even though he's had a growth spurt from age 13 to 16, he's not exactly what you could describe as being "buff".
NOTE: I'm playing Sothe from the end of Fire Emblem 10, Micaiah Support A (but I've kind of taken my own approach on how to deal with it. See Concrit Post for details!1)
