Only having one of something makes it automatically unique, and therefore special!
That One Index is for irritating video game things! Usually YMMV! High overlap! The Two-in-One Tropes are about tropes where two things are combined to form a bigger thing, with some overlap with this where the full object's singularity is important.
Sub-indexes:
- Uniqueness Tropes: For unique things. Also has its own sub-tropes.
- One-Liner: Single Lines!
- One-Shot Character: Character that only appears once!
- Solitary Tropes is a sub-index because being alone automatically creates 1 of something!
- The Singles Index is for romantic singles only!
