Julie Yamamoto is Ben's primary love interest, and later becomes his girlfriend. She first appeared in Ben 10 Returns: Part 1 at Ben's soccer game and congratulates him. On their first date in Pier Pressure, she discovers Ben's powers, but much to his surprise, she finds it "cool." She usually wears a black t-shirt mostly hidden under a pink sweatshirt, and a white mini skirt. When playing tennis she is shown wearing white wrist bands, shirt, and skirt. In Fame, when Ben's secret was exposed, she kissed him on the cheek for some encouragement. In Hero Time, she was kidnapped, until Ben saved her life and called her "his girl" and she smiles.
