Could you be thinking of another character or show?
Perhaps you are thinking of:
* Hamegg, a fictional character in the manga and anime series "Astro Boy". However, there is no such character in the original Astro Boy by Osamu Tezuka. It's possible you might be thinking of a fan-made character or one from a later adaptation.
* "Hamegg" might be a misspelling of another character's name from the Astro Boy universe.
Please provide more context or details so I can help you accurately identify the character you are looking for.
