Our intrepid hero has joined the plucky rebellion! The rebels are a ragtag group of the downtrodden and the oppressed, fighting against the tyranny of the current leadership (but don't you dare give them any actual political ideology as a basis, they need to be generally "Rebels"). They don't seem to have concrete plans, but they talk a lot about change and fighting for the people

Uh oh! Our intrepid hero just watched as a group of rebels executed some of the tyrannical leader's soldiers. They're shocked! How could they do this? Don't they know that killing is what the tyrant does? The rebels laugh it off. It had to be done, they would've done the same to them

Oh no! Our intrepid hero was there for the deposing of the tyrant. The tyrant was executed by the rebel leader and assumes control, then immediately turns into the McCarthyist nightmare of Stalin. Now our hero has to save the kingdom from the rebels, who have turned evil by their taste of power!

Basically fucking hate how rebellion and rebels are portrayed in media. It's almost like a psy op how often rebellions are thinly veiled anticommunist propaganda, and how rebels are often portrayed as being as bad or worse as the current tyrant, they just hide it better

Just off the dome I can think of the Avatar series multiple times, Bioshock Infinite, and the Hunger Games series but I know it's basically ubiquitous
