The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
The Determinator does not discriminate between hero or villain or require a single-minded goal, it is simply that they continue on despite all opposition, beyond the point where most would have given up or died. Example: Alice The Drifter doesn't have any long term goals and would be the last to call herself a hero, but she's survived thirty years in the wasteland mostly by being too stubborn to die, despite the wastelands' best efforts.
Said trope frequently overlaps with tropes like Failure Hero (they never win, ever, but they survive) and Action Survivor (they aren't particularly remarkable in most senses, but they manage to survive when others don't by gumption and quick thinking)

A character often fails, but finds a will to get back up and go on despite the failures or even in the face of imminent death. The Determinator does not apply since the character is a villain half the time, nor does he doggedly stick to a single goal. What character type is that?
