White Stone / The Stone (in Tagalog, "Ang Puting Bato", or simply "Ang Bato") is a pebble-sized meteorite containing unknown and powerful properties that grants numerous abilities to whoever wears or swallows it. Narda transforms into Darna, and vice versa, by shouting out their respective names ("Darna" to become Darna, "Narda" to become Narda). First, however, Narda has to swallow the stone, which conveniently comes out of her mouth every time Darna changes back to Narda. It started in the 1973 film Lipad, Darna, Lipad! ("Fly, Darna, Fly"). However, it was not so in the comic book versions. The stone's appearance usually takes form of a small soft white pebble/mineral that occasionally glows, usually when it is trying to convey something to its bearer. This can be theorized that the stone is also a sentient material capable of feeling and judgement. In Mars Ravelo's Darna! Ang Pagbabalik (1994), the stone was forcibly taken from Narda, and due to the altercation, she temporarily lost her sanity. Once she regained the stone, it projects memories of her as Darna though flashes of light, an effort of the White Stone to restore her mind into its rightful state. Although the original comic book lore written by Mars Ravelo himself does not go into detail about the origins of the magic white stone (other than the Darna entity contained within came from the planet Marte), other iterations of Darna had their own explanation of how the magic white stone came to be. In the 1991 film, there is no origin for the stone, but it was shown that it could restore any serpentine-humanoid to its youth. The 1994 film version showed it came from heaven and it was given by an angel to Narda, because she will be the one who can stop the emissary of the Devil who will soon come to their world. In the 2022 TV series, the stone came from the planet Marte, as a gift to the most qualified individual, this was given to Zora (the first Darna) then was passed on to her half-human daughter, Narda. The White Stone is one of the most coveted objects of the franchise, in movies and series, the White Stone was fought upon for its possession, mostly by the enemies, to use its power for world domination. In the 1991 movie, the Devil wants the stone instead of Darna presumably to use
