The known GateKeepers of Dinosaur Planet are: The King EarthWalker, Garunda Te, Belina Te, and Gradabug.
The only known furture GateKeeper is Prince Tricky.
In Dinosaur Planet the GateKeepers had an even larger role then they did in Star Fox Adventures. The GateKeepers were refered to as Guardians in Dinosaur Planet and had a slightly wider range of powers then they did in Adventures, as the Spell Stones were unable to save the planet unless they were powered by the Guardians. Without power from the Guardians they would be nothing more then mere stones, and would be unable to give Krystal and Sabre access to either of the Force Point Temples.
