1x14 - Digimon: Data Squad

To stop Merukimon's further assaults on the human world, DATS authorizes Yoshi, Thomas, and Marcus to be dispatched into the Digital World. Unfortunately, their presence does not go unnoticed by Merukimon and a mysterious shadow, who quickly ambushes the DATS after their arrival. The attacker turns out to be a ten-year-old boy named Keenan, who harbors an intense hatred for humans.
