Other: Hero turns out to have had a plan all along, where just by fighting the villain loses even if they win the battle.
Second favorite: Talk no jutsu (only when well done)
Third favorite: World of Cardboard moment - I was just holding back because I didn't want anyone to get hurt or to cause collateral damage.
Fourth favorite: The hero just straight up loses. Now what?
Fifth favorite: Hail Mary solution - a wild, desperate idea that nobody normal would even consider! Dresden files does this often.
Least favorite: Just believe in yourself/morale boost victory. It's only acceptable when confidence failure was the whole point of the story, and all the other pieces were there. Even then I don't like it. Otherwise, it's BS. Like in Blue Eyes Samurai (an otherwise excellent show that avoids this trope) she's fighting the Irishman and the chips are down, all cheap tricks thrown, and she's getting crushed by a physically superior foe...and then she just decides to win, and suddenly she has the ability to win!
