Characters so intrinsic to the plot that they cannot die, except for in the final scenes. They can be wounded, so “bulletproof” may not be the best possible term. Some of the kids on the Internet use the term “Plot Armor.” One characteristic of war movies is the increased likelihood of a Bulletproof Character’s death towards the end of a movie.

Famously, the HBO series Game of Thrones initially appeared to have no Bulletproof Characters, killing its lead actor in the middle of the first season. Having no bulletproof characters can significantly increase suspense. One criticism of the flawed final season of Game of Thrones is that many characters were at that point clearly bulletproof.
