Frisk? I don't really know. I mean, my fallen child was named James (no particular reasoning, it's not my name). So I kinda saw Frisk as a dude, but once I figured out that Chara was the one I was naming things kind of got weird. I saw Chara as a girl but I named the girl James, because Frisk.

help Well, I fell into a similar "trap", but I decided to go with it. I didn't change Chara's name, not even between playthroughs. For me, they will remain a boy, who looks somewhat like a girl. Guessing from that their haircut resembles a bob cut, their parents may have expected them to be girls. Something along those lines would explain why didn't they get on well with other humans, or reveal their gender even to their adoptive family.

Or you can go reverse Mandark from Dexter's laboratory style, and assume that Chara is a girl, who was given a boy's name.
