The Lady Luck (ラストリゾート Rasuto Rizōto?, lit. "Last Resort") is a Keychain for Sora's Keyblade which appears in Kingdom Hearts, Kingdom Hearts Final Mix, Kingdom Hearts: Chain of Memories, Kingdom Hearts Re:Chain of Memories, and Kingdom Hearts Re:coded.
In Kingdom Hearts: Chain of Memories, the Lady Luck is the signature Attack Card for Wonderland.
Lady Luck's general appearance is based on hearts, clubs, spades, and diamonds, the four suits on playing cards. The shaft and handle of the Keyblade are directly connected and both are black with pink edges. The pommel is a diamond covered in a red and orange checkerboard pattern. The top of the guard is made of two clubs colored in a red and yellow checkerboard pattern, while the rest of the guard is a purple and red horseshoe-shape. The tip of the blade is a large, orange heart with a thin, red and yellow border. The teeth of the Keyblade are comprised by a large, red spade. The Keychain is very short, consisting of only two silver links, and its token is an Ace of Hearts card.
The Keyblade's English name is derived from the goddess of fortune in Greco-Roman mythology (Tyche in Greece, and Fortuna in Rome), who was known as "Lady Luck". Its Japanese name is a pun on the "Trump Card", a card that is used as a backup move to guarantee victory.
