Here is Sparkstalker, a Decepticon Firecon Saboteur. Like yesterday's Flamefeather, Sparkstalker was a 1994 re-release of a 1988 design, released exclusively in the European market. He turns into a fire-breathing monster with friction-activated spark effects, made more visible in this incarnation thanks to a body that included translucent plastic parts.
