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

Also Called

  • Mass Alteration/Control/Shifting


User can manipulate mass to make objects either light-weight or dense. Users who decrease their own mass can move easier through environments and not have to worry about planetary gravitational pulls.

Since gravitational influence is proportional to mass, changing it will also change gravitational influence strength. Gravitational attraction can also become repulsive if the user decides to make negative mass.





  • 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.
