Family HistoryEdit

At some point within what seems likely to be just the past few decades, some Mongfish family members, possibly before Lucifer, revitalized the Knights of Jove and helped them , by means of their Sparky mastery of biology, produce a viable, charismatic heir to the House of Valois and the legend of the Storm King. Who exactly was involved in the conspiracy and how is yet to be revealed.

How well (so to speak) the Mongfish survived the Long War and the Other War is also yet to be detailled, other than DuMedd's comment that "I never had any family before. I mean, that wasn't dead or missing. Or a head in a jar or something."


When the comic first mentioned Zola's full name, Serpentina appeared in the voice balloon until Kaja corrected it. When it the novel first came out the novel listed Demonica as Theo's parent. Presumably this will be corrected in future additions.

Due to similar features between Z and Theo and the way things were juxtaposed, some fans have mistaken the Iron Sheik for Theo's father. He is Z's father. Theo's father is unknown to us. Presumably Serpentina knew him quite well.
