In my own 'little' digimon story. The troopmon siege is a very dangerous rogue programming, attempting to convert ALL!
One of the Troopmon Army's most horrifying plans of attack is to take control of the Digital World's nursery, since any digimon that dies is reincarnated at these places. Meaning you'd conscript the freshly reborn, eventually cutting off any chance to stop them.

So yeah, Terrifying Toddler Troopers; military brainwashing is for all ages now.
