Trickmaster

The Trickmaster is a boss from Kingdom Hearts and Kingdom Hearts: Chain of Memories.

The Trickmaster was a special Heartless with the ability to steal people's memories. It was sent to find the Wonderland keyhole and destroy Wonderland's heart. It was also sent to capture Alice. Though it succeeded in the latter, the Trickmaster was defeated before it could destroy Wonderland. Throughout most of Kingdom Hearts's adventure in Wonderland, the Trickmaster is referred to as the shadows or as the darkness (especially by the Chesire Cat). The heart in the Trickmaster is supposedly that of the Queen of Hearts.
