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.
