Passive protagonist
A passive protagonist is a main character who mostly reacts to events instead of pursuing a goal, so the plot happens to them rather than because of them.
The clearest version of the test: if all your characters do is run away, they are passive. Fleeing is a response to someone else's initiative. Giving a character something to achieve — even a small, wrong, badly chosen objective — makes them active, and an active character with a bad plan is more readable than a sympathetic one with none.
The Fantasy Fiction Formula lists two related failures among the ways scenes collapse: the passive protagonist and the bystander protagonist, the second being the one who is present for the important event but contributes nothing to it. Both produce the same reader experience — an aimless progression that is hard to point at and easy to put down.
The most reliable fix is at the level of reaction. When something goes wrong, a character who cares makes a plan; wait and see is what a character does when the author has not decided what they want. So when a challenge lands, show the protagonist altering course — even badly, even into a worse position.
The related discipline belongs to the ending: do not let the protagonist win through the antagonist's stupidity, or through a rescue nothing earned. Victory has to come out of their own capability, or the passivity was structural.
