- This episode features characters from "RPG World", an old webcomic by Ian Jones-Quartey, and this episode serves as the proper finale to the webcomic. Originally, Ian didn't want any specific call outs on it but influences from his storyboard team changed his mind. The final comic page was done by Ian himself using the same ink pen material and scanner he used for the webcomic all those years.
- The title card resembles that of the Final Fantasy series' logo. Hero is also based off of the main character of Final Fantasy 7, Cloud Strife and Sora from Kingdom Hearts.
