Hardspark (Sparkdash, 1988)
Japanese ID number:C-313
A redeco of the SparkabotGuzzle, Hardspark transforms into a ROF Challenger 1 Main Battle Tank. By pushing him forward in tank mode, "cold" sparks shoot from his back end thanks to a friction-motor that also propels him forward.
It is worth noting that even though his arm-treads have spaces for small wheels to assist in rolling, he doesn't actually have the wheels, which can lead to the plastic being scraped off his arms, and even his chest.
