Lana Lang

The brat should have been scourged every day of her life.

She was like a three season love interest who stayed on for seven and a half seasons.

By the time of SV the whole girlfriend not knowing the hero's identity had become time worn, post SV shows Arrow, Flash and Supergirl have love interests and sidekicks in on the secret a lot quicker.

She's seems to be surrounded with people who are dangerously obsessed with her.
