Fatal Crest

The Fatal Crest is a Keyblade from Kingdom Hearts II. It is a prize received after beating the Goddess of Fate Cup at the Olympus Coliseum. The guard, chain and emblem are the symbol of the Underworld. The blade and teeth is a bony dragon head and neck, possibly representing the Hydra.

The Fatal Crest's ability is Berserk Charge. This ability allows Sora to attack continuously. This means that Sora cannot cancel a combo, but must keep striking the enemy until it is complete. It also gives the largest magic bonus of any Keyblade (except for the Winner's Proof, which is only avaiable in Kingdom Hearts II: Final Mix+), making it good for usage with Wisdom Form.

Other Appearances
The Valor Form edition of the Play Arts Figures comes packaged with Fatal Crest as one of the Keyblades.

Appearence
The neck of the keyblade appears to be that of a skeletal dragon, of which still has life in some of it. The keychain is the "Ceberus cup" cup in a miniture version, relating to the fact that you get it from a cup.
