Digimon Tamers
One day the Four Holy Beasts used the Digimon Entelechy, Culumon, to evolve the Digimon to Ultimate so they could stop the ravenous program. They were successful and the D-Reaper was locked away into the center of the Digital World. Years passed and the D-Reaper mutated and gained power, awaiting the day it would be freed and to continue its given task.

The Four Holy Beasts sensed the D-Reaper's growing power and began to prepare to battle the program again, but Culumon was transported into the Human World. The Digimon Kami Zhuqiaomon sent the Twelve Devas to recover Culumon, but met resistance from the Tamers. When the Tamers and Culumon made it to the Digital World the D-Reaper's Chaos was already beginning to spread, deleting anything it touched. With Culumon returned, Qinglongmon told the Tamers to return to their world, but this was what the D-Reaper wanted for the D-Reaper had possessed a human girl named Katou Juri.

The Tamers returned to their world and the D-Reaper started to infest Shinjuku. After a long and grueling battle the Tamers and the Four Holy Beasts with the help of the Wild Bunch and the Ultimate Digimon devolved the D-Reaper for good.
