Cosma is the Omnitrix's DNA sample of a Celestialsapien from the Forge of Creation in Rex 14 Rebirth.


Cosma is a humanoid alien whose entire body is solid black, excluding his hands, which are white. He has tiny white star-like spots all over his body, giving him the appearance of a starry night sky. His eyes are blue and lack pupils, and his forehead bears three horn-like protrusions. His starred body isn't simply 'aesthetic', but Cosma, and by extension all Celestialsapiens are, or contain their own 'pocket universes'.

Powers and Abilities

  • Cosma is omnipotent, being able to warp reality, time, and space with ease and at any level he wishes. Even his thoughts can become real.
  • Cosma can create time waves to reverse events
    • Cosma possesses telekinesis and is capable of deflecting energy attacks
    • Cosma can destroy a multiverse, but it would take six thoughts.
    • Cosma can bond his power with other Celestialsapiens if they agreed. 


In order for Cosma to perform any action, including simple movement and transforming back, all three of his personalities must agree to do so. This has proven to be a major weakness, as if the two celestial faces weren't interested in dealing with present affairs and wanted to finish past ones that weren't possible to deal with without Rex.
