Tesla Zap

Tesla Zap is the deceased mother of Jack Zap and Magnus Gauss, the mother-in-law of Ann and the grandmother of Tesla. Tesla was a wealthy woman of the Zap Estate, and her inheritance is caught in a three-way fight between Jack, Gauss, and Ann. While she has long since passed away by the start of the series, it is shown that she may live on through an AI in the Zap Estate, and has put a Thunder Dragon in the mansion's cyberworld to test who is worthy of it. A harsh and proud woman who shows great concern over her family's good name, she shows displeasure in Count Zap's failures in life and seems to favor Gauss over him, though in actuality she cares deeply for Jack.
