The Red Aliens are large red aliens with long tusks on their necks and they live on a red planet (Saturn). They are seen in Transformation and Troq. In Troq, they are demonstrated in a video as creatures being attacked by large robots called Locrix. In Transformation, Starfire goes on the planet Saturn and meets some red aliens, but due to her new looks, the aliens run away from her. During the mission to find Starfire, Robin and the other members visit Saturn and they use Beast Boy to communicate with them by using Beast Boy's feet and the red aliens were showing the direction where Starfire went.
