Growing up I always felt like Pocahontas. Still do sometimes.
My teenage years, friends always referred to me as Daria. Though I think Jane Lane seemed more like me.
I've always felt deeply close to Harry Potter. I mean, heck, he is an ISFP. Neutral good, with no alliance towards lawfulness or chaos. Always following his own moral compass.
Amelie a bit, too, when I was younger and socially awkward. Seems most of the Fi-dom's resonated with her.
Jon Snow, as well. Though I haven't really analyzed that one, too much. Maybe the not fitting in (with the Starks) thing and his inner emotional thought processes and his values (like helping out Sam).
