Team Back Attack is named after the organic chemistry reaction called Backside Attack but with the lovely innuendo of butt sex.
The three members of Team Back Attack were part of a chaotic neutral hacker crew until they were caught and imprisoned. After Leo took charge of the Solar Eye, he offered to waive their prison sentences if they agreed to work for him to dox (track down) No. 44 (Frey). After getting caught, the team must wear ankle trackers at all times, and are constantly confined in the Solar Eye HQ.
Before working for Leo, the three had never met each other in real life. Jay had always proclaimed to be a 14 year old girl which nobody believed. What really surprised them was Mel being the girl since "there are no girls on the internet".
