- According to a interview, at the time of Kai Production, Stephanie was unaware of being replace for DBZ Kai and onwards. Stephanie was deeply sad and hurt personally. Ironically she had no idea why she was replaced in 2010. Many Fans wanted her back to return as Kid Goku and Kid Gohan.
- This is a true story for fans of DBZ, If you have or had purchased Dragon Ball Z Budokai Tenkaichi 1 for PS2. Then you can select adult Goku’s Super Saiyan 4 form for the character encyclopedia. Ironically when you view the character profile and voice listings; his Japanese voice actress is correctly named. However his English voice actor is incorrect with a typo. On the video game it mistakenly said that Stephanie Nadolny was adult Goku’s voice for Super Saiyan 4 when in fact it was Sean Schemmel who does the role. This video game ironically predicted, that Nadolny would finally voice Goku’s Super Saiyan 4 form decades later in the anime series Dragon Ball Daima, except that she does it when Goku is young.
