Maxinia Agatha Gilliana Heterodyne Clay is the daughter of Punch and Judy, after Gilgamesh Wulfenbach restored them and improved on their original construction, apparently (and unexpectedly) allowing them to have biological children.
Maxinia is shown to be extremely strong for a baby, and dislikes 'baby-talk'. [1]
Maxinia's middle names would suggest that she has been named after Agatha Heterodyne and Gilgamesh Wulfenbach.
Possible relevant outside information[]
The character may be named Maxinia after Maxine Danger Wright, daughter of Cheyenne Wright.
