Temptress first met the team during Psyman’s stag-do in Las Vegas. There she was known for taking up Rich High Rollers, and using them to live the high life, even if they were married or had a significant other with them. Mostly her victims left with the slightly higher than usual Vegas loses. Nothing to cause too much bother for them, or backlash onto her.
Psyman himself was the victim of her pheromones, and she had him commit Powered attacks on the city, and to also take a couple of casinos to the cleaners. The part that seemed strange was how this all happened. After all, they looked like a generic stag do until that point.
The rest of the team were able to stop her before Psyman went too far. Unfortunately Half-Life hit her expecting her to be able to take a punch like most Powers. However, pheromones don’t make you stronger, and he broke her neck.
The team made sure the Las Vegas PD were aware of her powers and were treated properly. However, a few days later Link discovered that she had been transferred from the facility that was holding her.
