Ah, yes... Jim Lee's redesign for the little lady from the pages of Uncanny X-Men. I jumped off of the title shortly before he came on board. I was kind of put off by all the quasi-mystical "legendary heroes" things going on in the outback of Australia, and wanted to go try other things that were getting my attention in those days. Yet I still browsed the comics in the stands, and saw how they were writing the X-Men even while being a full-fledged Japanese comics fan.
Looking back, I think the "lady ninja" phase of Betty's comicbook existence is actually quite a part of her now. You summed up the character perfectly.
