Pixar's higher-ups almost rejected the prospect of including Pixar content in Kingdom Hearts III, as none of them were gamers or knew what Kingdom Hearts is or how popular it was. Theme park creative director Tasha Sounart managed to convince them on how popular Kingdom Hearts is, and pointed out that catering to the series' teen audience lined up with Pixar's desire to be seen as an all-ages film studio instead of simply being perceived as targeting children and their parents alone. Sounart noted that, while the Pixar studio members familiar with Kingdom Hearts did not need to extensively detail the lore to those that weren't except when needed, it was needed to be clarified that the Pixar characters would not be meeting one another, or any other Disney characters aside from Donald and Goofy, as Pixar has an aversion to crossovers and shared universes outside of their signature Easter eggs.
