Why does Prince Adam say “By the Power of Eternia” now instead of “By the Power of Grayskull”?
Once Adam was on Primus he stopped saying “By the power of Grayskull” and said “By the power of Eternia”. According to Jack Olesker (series bible writer) the line was changed because Adam was too far away from the power source and had to rely more on his wits than his brawn. However, the toyline suggests that the line was changed due to Castle Grayskull transforming itself into Starship Eternia in the mini comics.
