The Space Orbs are an extraterrestrial species, resembling floating glowing spheres. A group of them came to earth in the episode "Space Jammin'" where they challenged Grojband to a battle of the bands with their band known as The Orb Experience. The Space Orbs also possessed The Newmans so that they could play musical instruments and they stole Trina and her diary.
Space Orbs all share the appearance of being shiny, floating orbs, each with different coloration. They possess a white line that serves as a mouth which squiggles when they talk.
- G'ORB - G'ORB is a blue orb. He is the lead singer of a band called The Orb Experience and is always trying to act tough by being a big bad alien who always accepts every challenge someone makes, sadly he always loses. In the episode Space Jammin', he possessed the body of Carrie when they were going up against Grojband. In the episode Hear Us Rock Part 2, he returned and declared a rematch on Grojband and also threatened to destroy their world with a meteor.
- T'ORB - T'ORB is a purple orb. In the episode Space Jammin', he possessed the body of Konnie. He is constantly fed up with G'ORB impulsively accepting band challenges.
- Z'ORB - Z'ORB is a green orb. He also has taken a liking to making pancakes. In the episode Space Jammin', he possessed the body of Kim when they were going to battle Grojband.
- N'ORB - N'ORB is a pink orb, and has a female voice. When they went up against Grojband in the episode Space Jammin', she possessed the body of Lenny. She has a secret crush on G'ORB.
- L'ORB - L'ORB has never actually appeared in the show. He has, however, been mentioned by T'ORB in the episode "Hear Us Rock Part 2." He is presumably the father of G'ORB. His color is unknown but it is most likely blue because it would match the color of his son.
