After looking near all over the Heat Zone, Dorulumon tells Ian that other Code Crowns can track other so Ian fallows a signal and finds the Code Crown with Tactimon, (The same 1 from the orginal Xros Wars) Who has the Code Crown, Dorulumon then fight him and Ian then uses the Garurumon DigiMemory. Dorulumon then thanks Ian, then Ian gets Flamemon Knight to battle. The 2 team up. Ian then Digi-Xroses Dorulumon and Nefertimon. And they get the Code Crown. And things get worst.
