He is an upbeat & positive child, but his abilities are envied by the mansion-dwelling criminal Hamegg. Hamegg enlists the help of his friends, the scientist Dr. Flau & the purple gorilla Gora, in schemes to outsmart, outdo, or even impress Astro & friends. In the end, Astro either succeeds against Hamegg or winds up working together with him.
