Infamous The King of Kong: A Fistful of Quarters character Billy Mitchell is suing Twin Galaxies for defamation.
Billy Mitchell and his legal representation actually filed the Twin Galaxies lawsuit back in April 2019.
Even if Billy Mitchell wins the defamation lawsuit, he will not hold any Donkey Kong world records, except for the first person to reach 1 million points, which now belongs to his King of Kong nemesis Steve Wiebe.
While The King of Kong documentary does not come out and directly call Mitchell a cheater, it certainly implies that he was up to something.
