Synopsis
On one odd day, Leroy, Kayla, and Conrad meet a 16-year-old alien girl named Madeline and they get in some crazy adventures

Main

 * Leroy (voiced by Dee Bradley Baker) - a well-meaning, intelligent, but rather daring 16-year-old boy who's pretty smart, but can easily get frustrated and angered. He is usually seen building all types of gadgets and gizmos in his room.
 * Kayla (voiced by Ashley Johnson) - a curious, but sweet-natured 16-year-old girl who is Leroy's best friend. She loves cute things like cats and is also pretty shy
 * Conrad (voiced by Rob Paulsen) - a naive, dimwitted, but strong 18-year-old boy who is Leroy and Kayla's best friend. He is basically the "dumb jock" of the bunch. Pretty strong, not too bright. Lately, Conrad got his driver's license and thankfully has enough common sense to drive a car.
 * Madeline (voiced by Vanessa Marie "Vannamelon" Pareja) - a hyper, kind, cute, bubbly, sweet-natured, happy-go lucky 18-year-old alien girl who became the trio's new best friend and is quite smart, and has a wonderful singing voice.
 * Sasha (voiced by Jennifer Hale) - a sassy, strict, but also caring, sweet, bubbly, attractive 20-year-old woman and Leroy's older sister. Even though they fight sometimes, she still loves Leroy the same. She also gives up her crush on Conrad, but considers him to be her best friend. She instead has a huge crush on Brandon, her colleague at her job at Mega-Shoppers, and sometimes gets freaked out by Madeline.
 * Ally (voiced by Amanda Leighton) - a sweet stray talking cat who roams around the neighborhood, and is loving to all people, especially Madeline. As of season 4, Leroy, Kayla, Conrad, Madeline, and Sasha loved her caring attitude very much that they decided to adopt her as their new pet.

 * Sid (voiced by Grey Griffin) - a weird 15-year old who is one of Leroy's neighbors as he sometimes stalks Leroy over his inventions, and STILL has a crush on Sasha, despite her preferring Brandon.
