Favorite Nostalgic Character
What I mean by Favorite nostalgic character is your favorite character from a piece of media that you experienced when you were younger but you haven't re-experienced the media since you were young.
Whether the reason be you just haven't thought to rewatch/play/read, or haven't caught up with more recent installments of the series, or fell out of love with it, or any other reason.
