- Youthful Freckles: Has these to indicate he's still a child like Betty.
Robot X- 5
- Voiced by: Bruce Hunter
- Androids Are People, Too: X-5 is treated very much as a member of the Galactic Guardians equal to Betty and Sparky, even if Sparky occasionally cracks jokes about his mechanical nature at X-5's expense.
- The Comically Serious: X-5 is much more serious than Sparky overall, but that doesn't stop him from being funny when placed in the right situation.
- Do-Anything Robot: He is equipped with all manner of weapons and gadgets, including some that are rather unpractical for a Galactic Guardian.
- Deadpan Snarker: He has a dry and biting sense of humour, especially when it comes to making fun of Sparky's recklessness and immaturity.

- Robot Antennae: Possesses a small, thin one on his head.

- The Smart Guy: His knowledge in math and science naturally make him the brains of Betty's missions.
- The Spock: Plays this role on the team. He refuses to accept anything that goes against his rational and scientific understandings and shows very little emotion.
- The Stoic: His emotionality is minimal at best. He did once upgrade himself to be more emotional, but his new personality ended up annoying his teammates so much they made him change back.
- Tin-Can Robot: Has a boxy, legless form that reflects the show's retro sci-fi sensibilities.
- Token Robot: He's the lone robot of the main cast.
