Carding or Ding is an orphan that wanders into the town of San Martin. He is played by child actor Robert "Buboy" Villar. There he attempts to make a living selling sampaguita. Shortly after arriving in town he is captured by Impy and made its host. Darna rescues him. Later reporters from Siklab Publishing Company interview him and Narda finds him, bringing him home to the Hospicio De San Martin orphanage. Narda insists on calling him 'Ding' as it sounds 'younger'.
He proves his worth to Narda when he saves her from two neighborhood hooligans harassing her. At first he is hesitant to make friends at the orphanage, believing friendship is fleeting-having experienced the loss of friends before. Carding is the one who has a felling that Narda is Darna. Then, one night, Ding secretly followed Narda. Then, Ding saw Narda turn into Darna!
It is later revealed that Carding believes his mother to be Marina, which we see in a photo Ding holds. It is later shown that Marina (who, unbeknowst to Ding is now mentally-disturbed and wandering the streets) is not the mother, but instead, his real mother is no other than Deborah, the manananggal. It remains to be seen whether he has powers inherited from his mother.
Being a streetrat of sorts, Ding knows how to protect himself. One of his weapons is a blow-arrow.
