Two very proud and aggressive creatures from the destroyed planet Inna; their race is made up of females only. Their star-racer is distinctive in that it is actually two ships that fly in tandem, but are capable of combining to form a more powerful craft. After combining their ships, they gain the ability to use an extremely powerful heat-seeking plasma cannon. Their star-racers are rectangle-shaped, red with a black border and, when it is two separate racers, are driven like motorcycles. The short-haired of the two, Skun, can make her fingernails grow into very long claws. She is also extremely strong, tearing a hole in the Arrow III's hull with her bare hands in the episode Nervous Like Ning & Skun. They want the ultimate prize to reunite their people, who are scattered throughout the galaxy. In the episode "Canaletto's revenge" the sisters challenge Kross for the last gate. Although it is never seen, the battle is witnessed from afar by Molly, and the fact Kross emerges victorious, emphasizes their demise. This proves to be false when in the final episode both are shown to have survived. Though Ning and Skun are known to be fierce, they also have a deep bond of loyalty to each other, as shown when deciding to compete to be the next Avatar, they didn't want to be separated. And when they were about to ambush Kross, told each other they had no regrets and that "whatever happens, I'm glad it was with you". In the Ōban Star-Racers artbook, it's said that Ning and Skun are close like lovers.
