Commish for @thebigboy71 featuring Etemon's past careers before sliding into evil.
In the Zone version of events, while Etemon does resurface as a reoccurring antagonist once again in the Network, having now Digivolved to KingEtemon, during Adventure, he's treated as more of a 9-5 villain who is actually pretty chill and more of a doting eccentric uncle. This is based on fandom observations that suggest they saw him as more of an ally that was simply on the wrong side for how goofy he was compared to the other villains, ... despite the fact Etemon is a more traditional cartoon villain who just enjoys being bad, but I do see the logic, hence my using of it here. Plus, besides Adventure: doing something similar, Etemon in other ancillary media tends to be more friendly, so even Bandai/Toei seems to have recognized this also.
This bit is also partly inspired by a joke in the old fan fic "Ticketed Items Only", an alternate telling of the Adventure story after they defeated Myotismon. While the fic did have a serious story in mind (one plot beat involved Matt discovering an extinct race of Digital Humans similar to Gennai and the DigiDestined having to fight a new villain with the power to mutate other Digimon into more destructive Digimon), it was largely forth wall breaking and jovial, having custom Digivolutions like "SonicBirdramon" and a reoccurring AOSTH Wes Weaselly type Digimon called Retailmon that assisted the DigiDestined with their current situation.
The beginning of the story would reveal Etemon had faked his death when fighting MetalGreymon, and became a Bob Ross like weatherman, much happier in his new life. That fic was a big inspiration for how Zone came to be, so bringing it back around was inevitable.
