Lunar x Gemini Pollux: seen to have an outgoing, bubbly personality. she seems to be interested in nearly everything, from rocks, to pizza. she's quite excitable and seems to be bad at cues, as seen when she chases Lunar around in her debut episode. she's also caring towards people she likes, shown when she was hanging out with Earth and when she was defending Lunar. Castor: seems to be mainly monotonous, keeping calm when asked questions by Earth and Lunar. he doesn't usually show emotion.
