May want to take a look at r/gameideas.

Obvious one is just playing as the villain -> carrion

A little cheesy but you could tell the story of someone becoming a hero, eg. One of this game where you work at the border and need to decide which people are allowed to get through and if you just play normally your shift ends and nothing happens, but there's also some human trafficking going on and if you pick up on it you can save the people and become their hero.

A game where you serve people in a cafe and have to juggle taking orders while daydreaming of being a hero, effectively playing to games at once. One where you take orders and one where you are the hero, could be like one of this flying games where you dodge the hero.

If you want more Ideas come up with them yourself.
