An image containing a single person. No one else should be visible in the image.

That means only one copy of the character. These situations should not be tagged solo:

• Single characters being depicted from multiple views (Danbooru post #12904)
• dakimakura which contain multiple views
• dual persona
• time paradox

These situations should be tagged solo focus, not solo:

• Pictures focusing on one character among a crowd of nondescript, less detailed people.
• Single characters engaged in sex acts with faceless or out of frame characters.

Situations that can be solo include:

• A single character with one or more inanimate dolls or photos of other characters.
• A single character with pet or object characters.
