3Below: Tales of Arcadia

Crown Princess Aja and Crown Prince Krel of House Tarron, two royal extraterrestrial siblings, flee their home planet of Akiridion-5 during a coup, along with their dog-like pet Luug and their bodyguard Varvatos Vex, and crash-land on Earth, specifically in the city of Arcadia Oaks, California. In order to return and retake Akiridion-5, which is being ruled by the evil General Val Morando, who has already dispatched a team of intergalactic bounty hunters known as the Zeron Brotherhood to find and capture the alien prince and princess, the aliens learn about human culture there and attempt to fix their spaceship (as well as to restore their nearly dead parents King Fialkov and Queen Coranda).[6] Zadra, one of the aristocratic defenders of the royals from Akiridion-5, arrives on Earth after looking for a way to halt Val Morando and locate the location where Aja and Krel are being held. Aja and Krel, meantime, resolve to exile Vex after learning of his role in Morando's coup. Vex is imprisoned at a bounty hunter base on the moon during his exile after being taken prisoner by the Zeron Brotherhood. After learning of his capture in Season 2, Aja and Krel set out on a rescue mission. But soon after the rescue, the group learns that Morando is on his way to Earth. After beating him, Eli, who has offered to serve as Earth's ambassador on Akiridion 5, joins Aja (now Queen), Vex, Zadra, Luug, and the rest as they journey home. Crown Prince Krel makes the decision to stay on Earth with his new human best friends after deciding that it has become his home.
