Noah Parker (voiced by Laurie Elliot) is Betty's best friend. He's an honor-roll student who enjoys studying mathematics and writing, which makes him a target for Duncan and Penelope's bullying. Unlike Betty, he's not very athletic, and the only sport he seems to be any good at is baseball. However he is shown to be a skilled skateboarder as seen in various episodes. He also has a strong crush on Betty, though she seems mostly oblivious to it, and he is generally jealous of whatever boy she's with. At first, he supported his father in his attempts to expose aliens, but later found it weird. At first, Paloma and him had their differences because Betty paid more attention to Paloma than him and he was deeply jealous of Paloma. He is also jealous of Dylan because of Betty's crush on him and his mutual feelings for her.


Noah was kept in the dark about Betty's dual-role as a Galactic Guardian until the end of the first season, though on numerous occasions in the first season he was close to deducing Betty's dual role (having hacked into her communications frequency using a satellite radio). He discovers Betty's dual role following the defeat of the villain Pandora; Pandora and her father had been sealed in a box and key, the key having found its way to Earth and into Noah's hands. The key had also teleported Noah into Maximus' lair. As Betty attempts to rescue Noah, Noah inadvertently causes the destruction of the Galactic Guardian headquarters. He is later rescued by Paloma, disguised as the Chameleon, and returns to Earth, where he manages to successfully convince Betty and Admiral DeGill to join the Galactic Guardians as a cadet.

Though inexperienced, he is very willing to go on missions (even begging Betty on numerous occasions to let him accompany Betty and her crew on missions specifically assigned to her), and he has saved the day himself on one occasion has aided Betty on her adventures in others. In "Scent of a Blugo", he, Betty and Noah go to the wrestling match. Noah had to distract Regeena while Betty, Sparky, and Robot X-5 fought off the Blugos. While in the stands, Regeena almost recognized Betty but then he gave her a full nelson to distract her, causing her to spill her drink onto her mask. In the end, Noah says he'll watch the next match at home, then gets a noogie from Regeena while Betty leaves the wrestling match. In the ongoing ending sketch "Crash Test Noah", he also acts as a human guinea pig for X-5 to test the various gadgets he invents.

While on Earth, Noah wears a white tank top, a blue jacket, green khaki shorts and red sneakers.
