Pollux is 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. After lunars death she became a bit more distant, only speaken when needed or spoken to. Tho shes still cheerful at times shes mainly quiet.
