HALO (group)

 HALO Heroic Anti-Evil and Lawbreaking Organization

What's HALO?
HALO is a good orginization, dedicated to fighting evil and crime. Their base is underwater, and one needs a submarine or special shuttle to enter it. Ironically, the ultimate embodiment of evil was buried beneath their libary. They were formed after AMEN was created, to destroy the evils of the world. In [ACRO], HALO was described as being in a calm, peaceful, mini-universe.
