Cubot is a good-hearted and easygoing robot. Even though he is supposed to be built with the same CPU as Orbot’s, he is somehow dim-witted and somewhat slow on the uptake; he has no concept of sarcasm (as evidenced by his reaction when Eggman flippantly told them, after Orbot asked if he wanted the remaining Wisps, that Eggman actually wanted them to go fetch him "a cheeseburger and a shake") and even when things are explained specifically to him, it takes a while for him to catch on.

While still a competent henchman, Cubot is talkative, not very serious, and generally annoying to those around him. Also, despite his devotion to his master, Cubot is lazy. Unwilling to take action until he is scolded, he actively tries to get out of doing any work.

Cubot's personality can be affected by whatever accent his voice chip is currently set to, causing him to adopt mannerisms and behavior associated with his accent.
