Franz Renoir was the king of the Canopy Kingdom, thus the husband of Nancy Renoir. Both of his daughters, Parasoul and Umbrella, inherited his red hair (somewhat, in the case of the latter). Known for his ruthlessness, he was responsible for much growth in the kingdom, but they were largely due to his many war campaigns. It was during this time that he authorized the creation of the Anti-Skullgirl Labs. However, his war efforts were put to an end when his wife became the Skullgirl. Although he was also responsible for the Labs' decommissioning, they were restarted in secret after his disappearance. It is implied that he was killed by Queen Nancy after she became the Skullgirl. However, his current status remains unknown.
- Some dialogue implies that the people of Canopy do not have a high opinion of him and his tyranny. For instance, in Eliza's story mode when Squigly voices distress and embarrassment over getting into a fight with the princess, Leviathan responds, "If she turned out anything like her father, I would not worry about it."
- Considering that Parasoul is referred to as the princess of Canopy and not the queen, King Franz may still be alive and his power has been surrendered to Parasoul.
- Early concept art shows that he owned a Living Weapon umbrella, Todd, corresponding with "Death" of the Four Horsemen of the Apocalypse. However, a weapon resembling Todd is shown in posession of Nancy and the weapon he is canonly shown wielding is of a completely different design than his concept art.
