* FridgeLogic: The kids' Sentinel forms are based off of constellations. This makes sense for the team Nimbar assembled to protect Earth. However, in "The Universal Hitchhiker", Orion reveals that he was a member of a previous group of Sentinels from another planet who were also based on Earth's constellations.[[note]]The other members were Draco, Ursa, and Leo.[[/note]] How does that work?
* IAmNotShazam: The team is actually known as the "Galactic Sentinels" within the show. The title is only mentioned during the first episode "In the Beginning...." as a joke to provide a TitleDrop.
* SuspiciouslySimilarSong: Compare the show's theme tune with "I Eat Cannibals" by Total Coelo.
