The power to manipulate the mass of objects or entities. Sub-power of Molecular Manipulation.

Also Called

  • Mass Alteration/Control/Shifting


The user can create/negate, shape and manipulate mass, making it be dense or absolutely lightened while also retaining the associated properties. Users who can decrease their own mass can move easier through their environment and needn't worry about the gravity of planets.

As mass determines gravitational strength, the user could gravitationally influence distance, matter and radiation as well. 





  • May be limited to manipulating the mass of either oneself, others or objects.
  • May be limited to only increasing or decreasing mass.
  • One has to be careful when increasing their mass too much to avoid becoming immobile.
