AEGIS

AEGIS (Artificial Extradimensional Guarding and Investigation Squad)
While not an officially sanctioned organization of the Japanese government, there is an element of rapport with law enforcement agencies at all levels so that AEGIS members are generally permitted to deal with troublemaking digimon without interference as long as they don't cause too much damage.

With DATS largely defunct, AEGIS has been conceived as an organization of chosen and allies that wish to ensure that law and order is kept on Earth in regards to Digimon. Currently, if a Digimon shows up here, all kinds of hell could be raised, especially if it's something greater than a Champion level.

This group of humans and digimon wish to be on the frontlines if any naughty digimon show up, and strive to eventually be strong enough to be a threat that even malicious Mega levels would have to deal with if they want to seriously do damage to Earth.
