Is yugi still the king of games in 5d's Yu-Gi-Oh if he isn't then who beat him?

Answer 1

The title King of Games no longer exists in Yugioh 5ds because the original series was set some time in the 1990s and GX was set some time during the 2000-2010 years and 5ds is set during the year 2021. As far as we know no one has beaten Yugi which is also implied several times by GX. The title King of Games is now called the World Champion of Turbo Duels, because they duel on Motor Cycles (called D-Wheels). When the show first starts off the current World Champion of Turbo Duels is Jack Atlus, who used to be the main character's (Yusei Fudo's) best friend until he betrayed Yusei and his friends and took Yusei's Stardust Dragon card from him and stole Yusei's D-Wheel and high tailed it to Neo Domino City. Yusei and Jack both used to live side by side along with others including Rally, and Crow, in a city known as Satellite. Satellite is a worn down city where the poor people and criminals live and they are stranded there due to segregation and discrimination by the people of Neo Domino City. Satellite was created during an incident that occurred 17 years ago causing the Old Domino City (Yugi's home) to split into two (Satellite and Neo Domino City). The incident was covered up with an Earthquake and Tsunami because if people new the truth then everything would become a bit too much for Sector Security to handle. Jack took Yusei's D-Wheel and ace card Stardust Dragon and left to Neo Domino City to become the King of Turbo Duels. Yusei eventually makes a new D-Wheel and goes after Jack only to find after confronting Jack what is really going on and the new threat that awaits them both.
