The Loonaverse is a complex world built up of three alternate universes, containing 12 girls. This can tie up with the Mobiüs strip theory, which we will discuss later.

The first universe, inhabiting Loona 1/3, is the most like earth. None of the members (Heejin, Hyunjin, Haseul, and Vivi) have special powers. However, Vivi is an android, but we will talk more about that later.

The second universe, inhabiting Odd Eye Circle, is the least like earth. All of the members (Kim Lip, Jinsoul, and Choerry) have special powers. Choerry can jump universes, Kim Lip can manipulate time and/or has super speed, and Jinsoul can teleport. In order to be in the OEC universe, one must have an odd eye. This means a different colored eye that lets you universe jump. Kim Lip's is red, Jinsoul's is blue, and Choerry's is purple.

The third and final universe, inhabiting yyxy, is what Orbits (Loona fandom) refer to as Eden. This is because, in order to escape, they must reject their universe, "Eden". They do this by accepting who they are, which is shown through the eating of their fruit. This unit consists of Yves, Chuu, Gowon, and Olivia Hye.

You may be wondering where the 4th girl, Yeojin, resorts. We will talk more about her later as well.
