Jennifer was born Kal-El on the alien planet Krypton, before being rocketed to Earth as an infant by her scientist father Jor-El, moments before Krypton's destruction. Discovered and adopted by a Kansas farmer and his wife, she was raised as Jennifer Lauren and imbued with a strong moral compass. Very early on she started to display various superhuman abilities, which, upon reaching maturity, she resolved to use for the benefit of humanity through a secret identity.
Fast forward to today, and Jennifer resides and operates in the fictional American city of Metropolis. As Jennifer, she is a PPC Account Manager for Periscopix, a fictional Metropolis PPC agency. By night and of a weekend, she fights crime, discernible by an appearance both iconic and distinctive; she usually wears a blue costume with a red-and-yellow emblem on the chest, consisting of the letter S in a shield shape, along with a red cape and red y-fronts, which unconventionally sit on top of her trousers.
Jennifer might tell the unknowing civilian that she is a regular girl with a regular past: a squash-playing, Devon-based gymnast with a penchant for advanced philosophical logic and distaste for travelling anywhere that is further than 30 minutes away, but do not let her fool you. The rewards you reap from a Jennifer-managed account are not from graft or human skill, but from alien magic.
