A (frequently male in western works) character has gained extraordinary amounts of power, and is no longer a mere mortal. He decides to show this by baring himself. Power Makes You Naked is when the character is completely nude after a Super Mode transformation or a One-Winged Angel stunt. It tends to cause a bit of symbolism of how they're inhuman, and therefore, don't wear human clothes. Frequently paired with Power Glows for censorship reasons, or with Anime Anatomy.
