Noah Parker is Paloma (alien) and Betty's best friend. He's an honour-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. 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.
Noah was kept in the dark about Betty's dual-role as a Galactic Guardian until the end of the frist season, though on numerous occasions in the frist 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 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.
