specifically trained and designed with a aged up Bart and Lisa Simpson. This model also produces Marge and Homer Simpson.
Montgomery Burns, Moe Green, Mister Smithers and Krusty the Clown Are also trained, but may require some inpainting to get perfect.

Model tends to work better when two or three characters are chosen. JSON style Extension helps a lot. This has been used with Forge Neo, I do not know how well it will work with Comfy or other platforms.
