Darna Dimakulangan is an elderly woman and the mother of Charles Dimakulangan.
Darna is first seen breaking up a fight between her adult children, Tala and Charles, berating Tala for criticizing Charles instead of supporting him. However, she suffers from random memory loss and soon forgets who Charles is, presuming him to be an intruder, so she slaps him. Tala reassures her and calms her down, but she doesn't recognize Charles as her son.
Later, at the climax of a confrontation between Charles and an imposter, she recognizes the imposter as her son rather than Charles. She berates him for letting their family's talisman be broken, and insists it is to remind them of their family's heritage. She tells him how proud she is of his accomplishments since coming to America, and when she hears the real Charles speaking in Tagalog, she leaves the imposter to speak with his "friend". Charles then kills the imposter, and Darna mourns the imposter as if her own son had died.
