It's always the silent ones who turn evil.
Lillia city was once a peaceful place, offering shelter and safety for everyone- that is until they had gotten themselves their very own villain, Jolt. The mystery girl always left a trail of bodies along the streets of Lillia city every single night, and was known for carving a heart into the shoulder of every person she killed.
Because of this, the population of Lillia city soon died down enough for the great city to become a small village. Jolt, in an attempt to find a new city to target, finds herself in Gotham city. After an encounter with the Clown Prince of Crime, she finds herself helping him kill Harley Quinn. Things had become even harder along the way, when Deadshot made an oath he would hunt them down and kill them.
