After being humiliated twice by low level villains Dee decided that she should probably just be someone's sidekick. She petitioned the Council of Hero's for a status change but she was told that the supers were spread too thin. Dee was advised to call for backup before engaging another Super.
The thing was that Jackal and Trickster didn't really have powers. They were just able to exploit her weakness, diamonds and her libido.
After the Trickster incident Dee added a solid plate to protect her vagina from similar attacks. But now she is sticking to low level criminals to build her confidence back up.
What Dee didn't know was that Jackal (whose name is Barry) and Wally were meeting with their friend Danny. Danny is also known as the Blur who has super speed.
Danny initially used his powers for good but after being snubbed by the council because of his lack of maturity he turned to crime. The Blur was fast enough to rob an armored car without anybody seeing anything. He mostly stuck to small crime, just stole enough for him to live comfortably.
Wally and Barry were bragging who embarrassed Dauntless Dee more and they were asking Danny to decide. After a few beers Danny said "Neither one of you. I'll show you how to humiliate someone. Remember that running back who fumbled the ball on the one yard line in the Championship last year? That was me. I had $5000 on that game."
Barry said "We all put $10,000 in the pot. The winner gets all." They all agreed. Danny started concocting his plan.
Dee was on her patrol in the industrial area. Daydreaming about someday landing a cushy sidekick job. The truth is, after her last two incidents, no hero wanted her. Well...except for Gigantia. But she got her last three sidekicks killed so she is banned from any more sidekicks.
Stopping at a red light at 10:00 PM is when The Blur made his move. He ran by and stuck an ice pick in her tire without her seeing anything. A half mile down the road she noticed she had a flat. Pulling over, looking at and cursing she began her 5 mile walk home.
