In the final fight between Baroque Works and the Straw Hat Pirates, Miss Merry Christmas and Mr. 4 fought against Usopp and Tony Tony Chopper. She was defeated by Chopper's Horn Point transformation. After blinding Mr. 4 with his Kemuri Boshi (Smoke Star), Usopp was able to escape from Ms. Merry Christmas and her partner's combined attack (Molehill Intersection Number 4), leaving Chopper to scoop her into his antlers.
