Earth Dimension L-291:
In this world, Rita and Lynn Sr. had only one child, Luna. So things were much less complicated for the Louds, financially, but this version of Luna still went to the Mick Swagger concert. But the difference is, Luna was still pained with the irritations of being an only child, despite all the love and joy from her parents, Lynn and Rita's love could never heal the painful loneliness of being an only kid. One day, Luna came across a wizard and told him all her issues with being an only child. Out of sympathy, the wizard gave her a potion to clone her. The price? Luna was successfully cloned, but she was cloned 13 times, all were aged down to 7-years old. The spell was permanent as well, which meant Luna(s) would stay 7 years old forever. And Rita & Lynn don't take the news too well, but eventually get used to having more kids, even if it meant being heartbroken about the thought of 13 Lunas will stay immortal while their loved ones will die... But, for each held-in sneeze, another Luna clone is created and it lead to 63 Lunas, nevertheless, Rita and Lynn Sr. try to do their best to raise all their kids...

Smart Luna (Yellow):

The smartest of all the Luna clones. She has glasses and braces on. She is often seen reading a book or doing some experiments. She puts more effort into studying rather than what Luna used to do in her life. She even tutors Clyde and Ronnie Anne on the weekends. But she rarely gets along with Angry Luna, Selfish Luna, and Evil Luna, and is often bothered by idiot Luna's shenanigans.

Idiot Luna (Gray):

The dumbest of all the Luna siblings. She can't even figure out how to set up a Chess Game. She often has been seen having a hard time remembering things, even the grocery list. Nonetheless, she gets along great with other Lunas. All except Smart and Angry Luna.

Nervous Luna (Teal):

This Luna is easily frightened by even the smallest of things, she's not really confident, and has a hard time not freaking out.

Despite her cowardice, she seems to be really caring towards others.

Sad Luna (Blue):

This Luna is depressed, looking on the bleaker sides of life, she's seen with mascara running and in tears, in need of a hug or comfort.

Evil Luna (Blood Red):

This Luna is manipulative, cunning and unpredictable, and pulls off pranks that even Luan would never approve of, which often sends people to the hospital. She doesn't hesitate to steal or come up with scams, bully or anything but Murder. She is anti-social with most Lunas other than Mischievous.

Lazy Luna (Orange):

The laziest in the group. She doesn't care what happens around her, as long as she does not have to do anything else.

Bossy Luna (Maroon):

The bossiest and strictest of all Lunas. She always makes sure everyone does their job around her.
