Where has the DCI gone?

The MCI are the main dead kids of the series and were the ones put to rest in FFPS. They are the Unwithered's, Classics, Funtime's and Molten Freddy, which means we went against them 4 times in the Clickteam era. Yet the DCI has had nothing. They are possibly the Toy's, but that brings up the question of where they went after FNAF 2. We do see their parts in FNAF 3, but that still asks where the DCI has gone.
