The superhero I choose is BatMan ,Batman has no powers so he uses weapons and stuff like that.
The name of the gadget is forc shield armer.
What the force shield armer does is protect the person that has it on so a bad guy hits Batman won't feel nothing but the bad guy will.
Batman needs this gadget because he doesn't have powers.
This gadget looks like a normal armer but it really is a for shield.
