A fight begins with moments later a Blast Evolution occuring when Ouryuumon is hit and with Kouta's encouragement for his Digimon to live. Ouryuumon's data makes a sword thus making Alphamon War King Dragon Mode. AWKDM attacks with his Ultimate Battle Blade Ouryuuken. Next Alphamon stands with Omegamon. They are preparing for a fight as Omegamon will delete the Digimon and that is his mission until the end.
