Around March of 2004, there was a company in Japan named Denki Batteries, which was very short-lived. As explained in the commercials which Austin restored, the Denki Batteries weren't as powerful as others, leading to their downfall. This advertisement shows an advertisement that includes a new character name “Rey”. If you were to go to the Denki Batteries website it would say that Rey is a mischievous person and a competitor to Denki Batteries who may have a crush on Denki (so basically a male tsundere that does a little trolling). As of right now no commercial that features Rey has resurfaced yet making this the only proof that Rey exists
