Hamegg

Ham Egg is an evil circus ringmaster who treats robots badly.

In the 1960's TV series, he was the one who gave Astro his red boots. However, at the time, his name was Mr. Cacciatore and he only appeared in the opening episode. He wore a black tuxedo in this version.

His character is changed very little in the 1980's TV series. In this version, his name is Ham Egg and he appears in two episodes: the opening episode, where he is dressed in a white tuxedo, and episode 2, where he is dressed in a black tuxedo [episodes 2 and 3 in the Japanese version].

In the 2003 series, he was named Grudon and, in contrast to the previous Ham Eggs, he wore a yellow tuxedo and was a rival of the Blue Knight. Ham Egg in the 2009 film is similar to the Ringmaster from Dumbo.

Ham Egg, voiced by Robert Axelrod in the English dub, also makes a cameo appearance in the 2001 film adaptation of Osamu Tezuka's "Metropolis" as a member of the Marduk Party, specifically as the lackey depicted to be the member closest to Rock where his demise is eventually met at the hands of Rock himself via gunshot wound, more specifically during the point in the film where Ham Egg escorts Rock to Zone-3 of Metropolis and upon discovering Tima to be alive and unharmed by his previous efforts Rock opens fire on Tima from a distance. This is met by the interference of Ham Egg pleading Rock to cease fire in the fear of equipment crucial to the city's functionality being damaged inadvertently to which Rock responds by channeling his rage through Ham Egg by means of reappropriating his line of fire toward him and proceeding to shoot him in the chest on impulse.
