Power Dyes Your Hair



You've just got a power boost. The reasons may vary, whether it's from going into Super Mode or your Super-Powered Evil Side deciding to wake up. Maybe you finally got your hands on that MacGuffin you've been after, or the Sealed Evil in a Can decided not to kill you after all. The point is, you're now capable of destroying the world three times over, and you can feel it.

The first thing your friend says? "Dude, nice dye job!"

Power Dyes Your Hair is Exactly What It Says on the Tin: a Power Makeover that applies exclusively to hair. The degree in which this happens can vary; on the one hand, a character may only have their hair change a few shades, especially if their hair's already light to begin with. Other times, a character may go straight from having Shiny Midnight Black hair to Hair of Gold or worse. Often, this is a good way for a character to maintain a Secret Identity, as the change isn't permanent. Bonus Points if Power Makes Your Hair Grow. May also result from Paint It Black, if the power surge isn't a good thing for the heroes.

Compare Locked Into Strangeness, which is what happens when the color change is permanent. A subtrope of Kaleidoscope Hair, when the color change can be for any reason. An Anime Hair trope, obviously.
