LEGO set 10375, How to Train Your Dragon: Toothless, represents Toothless from the How to Train Your Dragon licence.

How to Train Your Dragon: Toothless recreates the black dragon Toothless in LEGO form. The set belongs to the Icons theme, placing it among standalone models often linked to recognisable subjects, film properties and builds intended to work as display or collection pieces.

The build is therefore centred on the dragon itself, rather than on a wider scene with separate characters, scenery or a full play environment.

This set is suited to fans of How to Train Your Dragon, Icons collectors and builders looking for a recognisable model for display. Within Icons, it can be viewed as a licensed character model, focused on representing a single subject rather than expanding a minifigure based setting.
