Danbooru の英語定義
An alien species appearing in Ben 10. They are extremely powerful beings who can make any thoughts into reality if their two internal personalities agree upon a course of action; however since the two personalities inherently contradict each other it is hard for them to be able to reach a consensus or perform any action. They appear as humanoid beings with black starry skin. Alien X (ben 10) is the Omnitrix's sample of a Celestialsapien, with Bellicus and Serena (ben 10) being its two internal personalities, with Ben Tennyson himself serving as a third personality and tiebreaker.
