Operation Doodlebug

From DigimonWiki

In Digimon Tamers, Operation Doodlebug is a plan created by the Wild Bunch (Monster Makers) and Hypnos to revert the D-Reaper to its original harmless state. They would load the Shaggai (Juggernaut) program into Terriermon and execute it in the Transphotic Eddy, a light-speed spinning vortex inside the D-Reaper's mass that connected the Real World and the Digital World and also allowed for the fast evolution of the D-Reaper. This would invert the vector of the vortex and effectively degenerate the D-Reaper into a simple, harmless program. However, the fact that it would also force the Digimon to return to the Digital World was hidden from the Tamers.
