A formless, dangerous, nigh undefeatable, red mass in the Digimon Tamers series. Starting out as a simple program, it has mutated and evolved into a insatiable red blob created for one purpose: destroy anything that has overstepped its natural boundary. And it pursues this goal with deadly efficiency whether the target is digital or living.
Don't let the internet get to advanced...otherwise the D Reaper will kill it.
