Power Blonde

Strong blonde women aren't always evil. Sometimes, they're ambitious, wise, strong (even ruthlessly, but on the good side), rich, super smart, and overall confident. We can tell who is blond at heart because she doesn't try to hide behind anyone or anything. Often, a superheroine can be found in this trope because of how admirable she is in her universe for her power and sex appeal. She may be The Fashionista, but how she looks is just to bring attention to what she does. One thing's for sure, the power blonde is not the Girl Next Door. Can be among Plenty of Blondes.

Anime and Manga

 * Fate Testarossa from the Lyrical Nanoha franchise is a former Dark Magical Girl, who is counted among the most powerful aerial combat mages of the multiverse and works for the Time-Space Administration Bureau in the position of an Enforcer, giving her about as much personal authority in any dimension under Bureau's jurisdiction as a single human can possibly carry.
 * Even better example, perhaps, would be Saint King Olivie Segbrecht, The Emperor of Belka, who managed to stop a thousand-year-old interdimensional war in the Backstory and is currently revered as the resident Crystal Dragon Jesus. Unsurprisingly,.
 * Ai no Kusabi has the ruling class of "Blondies" as male examples. The top Blondie, Iason Mink, fits this to a T.
 * In Princess Principal, Princess Charlotte acts in public in a way that encourages people to mistake her Power Blonde hair for Hair of Gold. It wouldn't do for anyone to know her political aspirations.
