Slifer the Sky Dragon appears as one of the three Egyptian Gods in weekly Japanese manga publication "Shonen Jump." In this series of Japanese comics, Slifer is also known as "Sky Dragon of Osiris."
The three "Shonen Jump" Egyptian Gods, Slifer the Sky Dragon, The Winged Dragon of Ra, and Obelisk the Tormentor, are monstrous characters that may only be summoned by Pharaoh. Although Slifer is frequently mentioned with the other Gods, the character only made a few appearances in the comic series. Because of this, few of the series' trading cards featured Slifer, labeled as alternate artwork. Slifer the Sky Dragon trading cards are considered "ultra rare" collectors' items.
