Naoko "Gauko" Watanabe

Naoko Watanabe is a preteen with the gift (or curse!) of transforming into Gauko, a fire-breathing dinosaur girl when she gets too angry. She has bottom curly brown hair and black eyes. She dresses in a plain yellow dress top with a white collar and a pink skirt. Naoko is normally a kind and bubbly girl, however, when she becomes angry she transforms into Gauko. (Source: Wiki)
