Amongst her colleagues, Moonracer is the joy and the laughter. The bubbly little sister, Moonracer is full of naïve optimism and, to the dismay of her partners-in-guerilla warfare, pratfalls. She worries that others, either friends or enemies, don't take her seriously and dismiss her as simply being cute. But she'll show them. She'll show them she too can be hardcore.
According to Powerglide, Moonracer is the best sharpshooter in the galaxy.
The Transformers cartoon
Four million years ago, Moonracer tried to board the Ark, while it was being attacked, with the rest of Elita One's team. The plan failed though, and she and the others appeared to be destroyed.
Moonracer was part of a team of Female Autobots on Cybertron, long believed to be extinct. While stealing energon from a Decepticon stockpile with her teammates Firestar and Chromia, Moonracer tried to take more than they needed and, in the process, tripped an alarm.
Shockwave thus discovered that the Female Autobots still existed and, by sending drones after them, was able to estimate the location of their underground base. Shortly thereafter, in an attempt to capture the squad's leader, Elita One, Rumble used his piledrivers to cause a cave-in inside the Female Autobots' underground base, trapping them there. It was Moonracer's idea to detonate the energon cubes they had stolen, and that she had stashed away safely prior to the attack, in order to blast their way out, which proved to be a succesful plan. In search for Elita One, they met up with a few of the Earth-stationed Autobots, who had come looking for Optimus Prime. Among them also was Powerglide, a friend of Moonracer. As the Earth-stationed Autobots were in a fight with the Decepticons, Moonracer and her colleagues immediately came to their aid. This temporarily turned the tide, though it was not until the arrival of the two missing commanders that the Autobots managed to actually win.
With the Decepticons defeated and their underground headquarters destroyed, Alpha Trion relocated the Female Autobots to a new base of operations.

Moonracer, Firestar, and Arcee were strolling around on Cybertron after a battle, when they were attacked from behind by a Decepticon. Only Arcee was quick enough to respond in time, blasting the attacker before her friends came to harm. She then chided her teammates, noting that "War seems to be too tough particularly for females" (sic).
Later, Moonracer, Firestar, Chromia, and Elita One celebrated their victory over an absolutely gargantuan Decepticon warrior. Well, Elita brooded, but the others celebrated.

Moonracer and a few other female Autobots were an elite squad of warriors under the command of the Quintessons.
- Moonracer was originally going to be part of the BotCon 2005 convention exclusive "Descent Into Evil" set, but Hasbro was unable to secure the trademark to her name, discovering this well into the toy's production. Fun Publications changed the toy's character to to Chromia, the first name on their list of alternates that did clear, even though it was their "third or fourth choice".
