I use this Digimon to attack an opponent's Digimon, then use this Digimon's effect to reduce the opponent's Digimon to 0 DP. What happens to the attack?

Official Ruling
No battle occurs, and the attack ends. If there are other When Attacking effects, "when one of your Digimon attacks" effects, and/or effects activated at blocker timing, they activate, and then the attack ends.
