Orbot & Cubot are the closest things Dr. Eggman has to friends. They’re not perfect, but they are loyal… While Cubot is the funbot and Orbot is the stiffbot, they’re an inseparable pair.

Orbot is the spherical one, and his smooth surface goes with his polished demeanor. He speaks calmly, formally, and without a filter. He’s honest to a fault and offers unsolicited, withering assessments of his master.

Cubot is the blocky one, and his sharp corners match the rough edges of his personality. Like Orbot, Cubot says things Eggman doesn’t want to hear, but less diplomatically. Cubot is gruff and gritty, like a beat cop.
