Darna

Darna's first adventure (as Darna) was first serialized in the pages of Pilipino Komiks #77, where she was pitted against the sultry snake goddess Valentina. Here, Narda, a young girl, swallows the stone, which has the word Darna on it, and transforms into Darna by shouting out the latter name. Likewise, Darna turns back into Narda by shouting her name. The stone, from the planet Marte, stays in her body, and her secret is known to her grandmother, and her brother Ding, who becomes her sidekick. The superheroine quickly gained popularity among Filipino comic book readers

Starting in 1951, several Darna movies were made. Some made from 1973 onwards starred the future multi-awarded dramatic actress and politician Vilma Santos. In these 1970s films, Darna's origin was changed; no longer a little girl, Narda was now in her late teens. Also, she herself becomes Darna, unlike the original where she just "channels" her (not unlike Jason Blood and Etrigan). Only Ding knows her secret in this version. Also, the stone comes out of Narda's mouth every time she changes back; she has to swallow it every time she wants to transform (This became standard for following versions). Darna is not specified as coming from Marte, just as a "warrior of Light". This version of Darna became most people's idea of the character for about 3 decades. A catchphrase popularized by the movies and said by Narda runs, "Ding, ang bato!" ("Ding, [give me] the stone!")
