I am Adam, Prince of Eternia, and defender of the secrets of Castle Greyskull. This is Cringer, my "fearless" friend. Fabulous secret powers were revealed to me the day I held aloft my magic sword and said, "By the Power of Greyskull!"
Psst. Hey buddy. Here. This is a magic sword.
Magic sword? Riiiiight....
Yeah, all you have to do is hold it over your head and yell "By the Power of Greyskull."
