I was very, very young, but Scully from the X-files.
The only reason I remember this is because I don't have a habit of having crushes on fictional characters. I was more of a shipper if anything I guess. I mean I had lots of fav characters, but not many crushes.
OH YEAH
Billy from Power Rangers. I duno, he was cute, I liked him.
As for cartoon characters crushes?? I duno... most likely Storm or Aqua Lad
Although it's kinda an ongoing joke that Lightning (FF13) and Raiden (MGS) are my waifu's I don't know how that started I think my younger sister decided it and I just accepted it like "hell yeah they my waifus"
