Trivia

• Despite being the toughest armor in the game, it never sees any real use as it is found right at the end of the Genocide Route, and Sans, the last enemy of a Genocide Route, always deals one damage.
• The Check flavor text alludes to Genocide Route's ending, where the protagonist's SOUL is given away.
• The Locket is the only item in Undertale to include "the" in its name. In the Japanese localization, this emphasis is maintained by changing the line "You got The Locket." to, approximately, "Took back the locket."
