What's your headcanon on propaganda throughout the Lylat System?
To understand the propaganda, let’s first talk about some headcanons I have regarding politics. So I see the Cornerian Empire as spanning over several planets. Notably Corneria, Katina, Papetoon, Eladard, Macbeth and Zoness. There are colonies on at least Fortuna, Aquas, and Fichina as well as some space colonies in orbit over certain planets. While each planet is guaranteed to have a local government, some planets who were taken over by Corneria more recently than others still have vestiges of their former original governments in place-- usually by the blessing of Corneria, who really only expands for authority purposes (regulation of certain goods, making sure planets behave themselves, etc) and for resources (this is especially true as to why they targeted Eladard and Macbeth). A good example of this is Macbeth, which was brought into the Cornerian Empire relatively late and still has a lot of its old leadership intact, including its former president.
Some people view Corneria as a sort of inevitability-- someone will be the strongest out of all of the planets and although the Cornerians are prideful and maybe a bit egotistical, they do an acceptable job for the most part. So certain places, you see a lot of pro-Cornerian propaganda. Usually the places that have been in the empire for the longest. “The Cornerians will help keep us safe”, “The Cornerians have the best technology, they can stop any threat”, etc. The Cornerians are sure to ham this up the best they can where they can to keep their loyal citizens content and worry free.
In other places, there’s a lot of resentment and that resentment is amplified by propaganda from underground anti-Cornerian movements. Eladard, despite once being a land of booming resources, got sapped dry by the Cornerians prior to the Lylat Wars and was left with a paltry defense force that largely got bought out by local crime lords, letting them run amok while the Cornerians focused on Andross. Andross tried to exploit some of these anti-Cornerian movements to his favor and that did help him get quite a few allies among the various conquered planets.
So the propaganda that people would see across the Lylat System would kind of vary depending on where you lived. Some people would see the anti-Venom propaganda. Some people would see anti-Cornerian propaganda.
That being said, a lot of pro-Cornerian propaganda is especially strong on Corneria-- which should not be terribly surprising. There’s a lot of emphasis on patriotism and doing things for the “greater good” of Corneria. Particularly in the military, which has a strong presence in how things are run.
