The Heart Locket is an armor item found in Asgore's Home. It replaces The Locket when the protagonist is outside the Genocide Route. Its offensive counterpart is the Worn Dagger. It is the Neutral/Pacifist Route armor item associated with the First Human.
- The message "Best Friends Forever" is implied to be of the First Human and Asriel.
- It is speculated that the Heart Locket is the same as its counterpart, The Locket, found on the Genocide Route. The protagonist likely does not know its real value and sees it as a generic locket. The First Human, however, knows its true value and feels reunited with their Locket.
- Ironically, lockets in typical RPGs are considered a useless starting armor.
- Asriel, in his God of Hyperdeath form, also wears a heart-shaped locket.
