Slifer the Sky Dragon is the second God card revealed. It was one of the two God cards owned by Marik, who gives it to one of his mind slaves in an attempt to defeat Yugi. Yugi defeats the slave, however, and claims Slifer as his prize. Although reluctant to use Slifer due to its vast power, Yugi places it in his deck during the finals of the tournament due to the threat presented by Kaiba and Marik's own God cards.

Slifer makes sporadic appearances after the Battle City arc. It is used in season four of the anime to battle the Leviathan, and in the final season it battles Bakura's Diabound, but Bakura is able to weaken and destroy it by having a brainwashed priest attack the stone tablet housing Slifer's spirit. During Atem's final duel with Yugi, Slifer is Atem's final summoned monster before the duel ends.

Slifer's attack and defense scores are equal to the number of cards in its owner's hand times 1000.''[[Yu-Gi-Oh!]]''. Episode #66. January 05, 2008. Whenever the opponent summons a monster when Slifer is on the field, Slifer's 'second mouth' can lower the Summoned monster's attack by 2000; if the attack consequently becomes zero the monster is instantly destroyed.

This English dub adaptiation of the card has the name "Slifer", which comes from Roger Slifer, the co-producer of 4kids. The original name of the card in Japan is "Osiris".

Slifer made a brief cameo appearance along with [[Yugi]] in [[Bobobo-bo Bo-bobo]]
