History during the Lost Seasons
This season starts with Joey Wheeler lost in a Virtual Reality challenging who would later become Grand to a Duel to return back to Earth.
Grand wants a human body (because he has the body of the "Felgrand Dragon") to escape the Virtual Dimension he and Joey are in but can only get it if he defeats Joey in a duel.
Grand ends up being defeated but he escapes somehow from the Virtual Dimension.
After that,he appears on Earth after the 7 Tournaments are finished and takes Yugi Muto to the Island of Dragons to transform him into a Dark Duelist thanks to Bakura who secretly works for him.
It is unknown how but Grand gets himself a human body and a new Deck,which he finds in a cave.
Shortly after he invades the Island of Dragons looking to recruit people from the island by forcing them into duels and defeating them.
He then sends his Felgrand Armies, (many of which are defeated by Joey Wheeler) after unwelcome guests on the Island such as Yugi Muto,Joey Wheeler,Riot Gensutku,Rakum Gensutku,Seto Kaiba and Yuel,who are all defeated by A.G. after the Felgrand Armies fall down.
He almost gets challenged to a Duel by Yugi Muto but before that happens, Yugi is consumed by the Dark Desire with Joey facing Grand instead.
During this season he uses the same cards as the ones found in the TCG Structure Deck:Zombie World.
After the Felgrand Armies and the Duel Guards are defeated, Grand sends his final weapon, the Ancient Masters after Yugi Muto,Joey Wheeler,Seto Kaiba,Riot Gensutku, Yuel and Rakum Gensutku before they have a chance to finally defeat Grand in Duel once and for all.
