Lol, well, I just have soo many characters, and it's not that they don't have a personality that can be easily understood, it's just I haven't explained it yet, lmao XD in the case of Natasha, she's from an ongoing story where she isn't the main character (they are actually Light and Umishin, whereas she's considered a main supporting character).
I never roleplay with my characters unless they were MADE for RPs, lol. I mean, it's not that I won't, but most RPs don't have the same settings I need for them, lol. I abuse the RP Epitome of Silence (currently have 7 characters), but all those characters were mostly originally made for that RP. Tanel was made for RPs looong ago, and then he got put into a story with two other characters that, lo-and-behold,a re also PC characters in the RP (belong to the other 2 admins). We're gonna make a manga off of it one day...once we finish the storyline, lol XD
