The Earth generally has a bright personality. He can be a very welcoming planet, as seen when he greeted Astrodude to outer space. And yet, he is shown to be very insecure, short-tempered and over-dramatic, like when he tried different methods to replace the Sun and blamed the moon for drifting away despite it being more his fault. The Earth is also a self-centered, obnoxious, and curious planet at times, and doesn’t treat others with respect.
