Dee Shvagenbagen.

Dee looks a lot like her father, with blond hair (albeit a slightly brighter shade, likely influenced by the brighter shade of her mother's hair), blue eyes, rectangular jaw, and slim silhouette, but she also has her mother's curly hair, freckles, and round nose.

She wears her hair mid-length, tied back in a low ponytail with a strand falling over her face. She usually wears a black T-shirt under an unbuttoned white jacket with the sleeves rolled up, blue-gray pants, and black boots. She also sports several accessories, including black bracelets and bangles, dark eyeliner, a black choker, and two helix piercings. She is almost always seen with a tired and somber expression. She also speaks with a deep, nasal voice.

Much like his appearance, he closely resembles his father, having his calm disposition, high intelligence, and sadistic tendencies, but he also has his mother's hostile attitude and bad temper.

In "Protector", we see Dee helping other students cheat on their tests for money and defending his younger brother, Heavy, from Chipmunk. This shows how he uses his intellect to make money and profit, and helps establish his role as a caring (albeit unadmitted) older brother. These traits are further reinforced in the series, where we see him use his tech skills to wipe cameras of incriminating evidence against his mother and fabricate false evidence to incriminate those who pressed charges over illegal video footage. Dee also has access to the school's security cameras, as shown in the episode "Lif". In this episode, it is also hinted that he has a history of blackmailing students and making deals, though he always keeps his word.

Dee is also an excellent liar. He's a cold boy.
