This is Mew Mew Peppermint, and she's shamelessly holiday themed.

She's American; her regular name is Patricia 'Patty' Whitedrift. Tried to do something clever with the whole bit about Mew Mew names being related to civilian names, so Patty is a diminutive based on peppermint patty.

Her genes are Reindeer (Rangifer Tarandus), 'cause I'm a hack.

Her weapons are a pair of handheld jingle bells, Peppermint Sleighbells; associated attack Ribbon Peppermint Avalanche.
