One of the missing Queens.

The Queens are the four missing cards that Edgar Teglee needs in order to finish his house of cards so he and Razputin Aquato can go into the sky within Black Velvetopia in Psychonauts.

When Razputin notices the cards missing, he sets out to find them within Black Velvetopia. Whenever he finds one, it's snatched up by one of the Luchadores. Razputin must then engage them in battle. Whenever a Luchador is defeated, it's revealed that the arena itself was the card.
