Digimon 02
In the Digital World's "Death Valley" (Land of No Return in dub) where the latest Control Spire was, the sand sucked in Yolei, Hawkmon, Cody, Armadillomon, T.K., Patamon, Kari and Gatomon in, leaving Davis and Veemon untouched. When encountering the Digimon Emperor, Davis' friends were suspended from the ground over a Deltamon under the control of the Digimon Emperor's Dark Ring. When the Digimon Emperor asked Davis which of his friends he will have spared from Deltamon's triple appetite, he wanted to be fed. Suddenly, Digmon appeared with the rest of the Armor Digimon (Halsemon, Pegasusmon and Nefertimon) and the Real DigiDestined. The fake ones were really Bakemon and they attacked. Davis was mad about being tricked and Armor Digivolved Veemon to Flamedramon. When the Digimon Emperor was attacked by Davis, the Digimon Emperor ordered Deltamon to destroy him before Flamedramon destroyed the Dark Ring.
