 In the year 2058, Cosmo came into the world. At the age of 3, she had her coronation, making her crowned princess of Morph. After Iveus attacked the kingdom, she was sent to earth with her newborn brother, 70 years into the past.

Now in the year 1951, upon being found by a teen couple, Cosmo and her brother were taken in by a doctor named Mio and her husband Clayton, who took them in as their own, though having 3 biological children already. She would grow up knowing nothing about her origins, though grew up in a healthy household and eventually got through a year of high school before getting a small job to make money of her own. Her adopted father would buy a used truck off one of his employees and hand it down to Cosmo, as she had signed up for the military and was moving to Westport with her brother.

Moving to Westport, they slept in the truck before she saw a place for rent. Upon meeting the man who was renting it out, she begged him that she had little money to pay him and that they drove nearly an entire day to get there to look for abomination. She was happy that he gave the place to her free of rent, since her words made him feel remorse for her long travels. She and Buzz moved in immediately, getting comfortable just under half a week.

Four years later, she would join Star Command after the former Commander heard about her amazing feats, keeping her rank as Captain and getting her own ship built in her honour, which still sits at the Star Command base on earth. Upon joining star command, she accompanied her brother who attends Space Ranger training, graduating beside his new friend Alisha. They become rookies and rise through the ranks, Alisha, down the road, becoming Commander and Buzz, after Cosmo kindly begging Alisha, becomes captain. Cosmo, supportive, yet slightly bitter about not being a Ranger, would be Buzz's right hand. When leaving earth on the Turnip, she remained serious as a lieutenant, however becoming annoyed when others poke jokes about not being like her brother.

When they make a detour to T'Kani Prime, Cosmo sets off to explore the planet, finding a blue Crystal Star. It disappears from her sights after bringing it closer, hearing commotion coming from the direction Buzz had gone just moments before, she rushes back to the ship, only for her to teleport back into the Turnip with Buzz and Alisha in toe. When they take off, she is in one of the hallways, before Buzz over calculates, clipping the ship in the cliffside, sending it plummeting down, Cosmo flying upward, before it crashes down to the ground, sending her forcefully back down the hallway into the wall, knocking her unconscious. Upon waking up, a few days have gone by. She would eventually be on her feet again, supporting Buzz and his mission to achieve hyper-speed travel. However, when it fails, she is determined he can do it, watching as Alisha got engaged, had a son and eventually grew old, passing away later on. She takes it upon herself to solve the problem herself.
