Skull-Queen of Skral

One of Agatha's innumerable ancestors, mentioned by Castle Heterodyne as it attempts to point out to Agatha that Gil's dispatching Vole to retrieve her doesn't exactly disqualify him as a suitor. Quite the contrary, Vole is pretty small potatoes compared to the "two hundred warrior homunculi" that she sent to get the attention of Dagon Heterodyne. It apparently worked, as Her Cranial Majesty is reported as one of Agatha's ancestors. Other than this little vignette, we don't know much about her.
