Once found what powers were connected to this alien vest, he decided to begin the new occupation of hired assassin, by the name Sidestep.
Creation

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.
