Not to be confused with the human leader of Astro & The Space Mutts three years earlier, this Ace (Jim Piper) suffers from the same kind of malady as was seen in the live-action Big John, Little John in the 70's. At the most inconvienent times, due to being exposed to an Infanto-ray, Ace morphs into a young boy named Dexter (Sparky Marcus), which frustrates Officer Kimberly (Nancy Cartwright, in one of her earliest toon roles).
The concept of the Space Ace video game came from veteran animator Don Bluth, whose other video game, Dragon's Lair, was also adapted for television by Ruby-Spears, albeit for ABC, but also lasted one season.
