Damsel in distress
Damsel in distress is an extremely common trope in fiction where a female character requires a male character to save her. Although I don't have a problem with the damsel in distress trope by itself, I find the fact that it is so ubiquitous in fiction a bit troubling, and I much prefer strong female characters.
These are works which feature a damsel in distress that are important to me. For the complete list, see the damsel in distress category.
