The power to have a fixed speed while moving. Sub-power of Mobile Invulnerability.

Also Called

  • Constant Speed
  • Partial Unstoppability


The user has a fixed speed when moving, meaning that their speed is always constant, nothing can slow/stop the user, and they can't be sped up. However, their direction is still changeable, so a strong enough or applied-for-long force can change their direction of motion of the user.



  • Can be stopped by Absolute Defense.
  • May require high speeds for power to be effective.
  • May require extreme size, or mass to be effective.
  • May be defeated by momentum redirection, effectively using their own power against them.
  • Is still able to be changed in direction, so is not truly unstoppable.
  • May not be able to be sped up.
