Where the Wonder Women Are: #19 Lady Sif
Sif first lost Thor when he was banished to Earth by his father Odin in the 1960′s. She then had to cope not only with Thor playing superhero (and fake doctor, bizarredly) for years and forgetting all about her, but also with him later returning to Asgard with his new human honey Nurse Jane. But Jane’s brief immortality was retracted by Odin who then set Thor and Sif up on… well, not so much a blind date as a blind monster battle. They fell for each other all over again while killing monsters, and pretty much continued killing monsters together for most of their relationship. Hey, it’s romantic for THEM!
