"Time for a trip to the recycle bin Phantom. And then once you're in the recycle bin, im going to right click on it and click empty recycle bin. Because otherwise you would just be taking unecessary space. In other words, i'm going to kill you." - Kaiba's words to the Phantom prior to his death.
The Witty Phantom is a character in KaibaCorp's MMOCCG. He captures Seto Kaiba and lets the fangirls see Kaiba in chains.
The phantom is the boss of the game, if the dragon is not released.
Mokuba rescues Kaiba, and the Phantom is subsequently deleted.
