Zee Smith, a young man who can pass as Ro's guardian if anyone becomes suspicious of the pair, is Zeta's favorite human guise. Ro is actually the one who modeled Zee's features into what they are- and she couldn't have made him any cuter! Although Ro clearly thinks he's handsome she's a little less than enthusiastic about some of his clothing choices. He's still working on the whole fashion thing.

Although Zee blends in with the crowd much more than Zeta's real appearance would allow, he is still very naive about the world around him and often displays behavior that others find strange (like smelling flowers with the top of his head, since that's where his olfactory sensors are located). Zee is kind of stiff and doesn't use many facial expressions, which only adds to his oddness. Luckily, Ro is always there with an excuse for his brow-raising actions.
