Bombians are citizens of Cubebomb. They are everyone in the community, and they are every CB player. Your Bombian is a square person. There are many colors you can choose for your Bombian, but once you choose your color, it cannot be changed.
It is also presumed that your Bombian will be your character in the Cubebomb game, but this has not yet been confirmed.
You can buy clothes in either the User Shop or the Official Shop. Afterwards, click "Change Character" on the left of your screen, in the sidebar with your name, and decide whether to use official or user-made items. Then, customize! Note: A Bombian's color is like its name, and it cannot be changed after it is chosen.
