Save the King

The Save the King shield has been Goofy's ultimate weapon throughout the Kingdom Hearts series, however the method of obtaining it differs from game to game. Donald has a similarly named weapon, the Save the Queen.

Kingdom Hearts
The shield is obtained by defeating the time attack variant of the Hades Cup.

Kingdom Hearts II
The shield is obtained by synthesis. For this shield you need Twilight Shards, Crystals, Gems and Orichalum. There is another variant, Save the King +, which has no difference in power, but has a different ability. It can be found in the Ship Graveyard in Port Royal.
