Gremlin

From publisher blurb: GREMLIN!! Remember that time that your hero's powered suit malfunctioned? Or maybe the time that heat pistol shot just lukewarm air? Did you think they were a fluke? If so, you were wrong. That was the work of Gremlin. Thief and corporate spy, this shrinking villain will not only steal your plans, but also cause them to go haywire!
