Powers and Abilities

The vest that Sidestep wears has the power to shunt objects and people into an out-of-space "stasis" until the wearer decides to bring it back at any point in space and time.

Along the stasis, the vest has also the power (eventually) of temporarily rearrange the minds of the captured subjects.
