The AD Police are an elite group of highly trained and specially equipped police officers who have been formed to deal with terrorist activities and Boomer robot crimes in the city of Megatokyo. They are more heavily armed and equipped (including power armors like the K-11 and K-12) for a normal police force, but too lightly for a military organization.

The AD Police are offered a great deal of leeway in their activities, often blockading large sections of the city and causing great amounts of property damage in the course of fulfilling their duty. Despite their dedication to their jobs, however, the citizens of Megatokyo tend to dislike and distrust members of the AD Police, seeing them as corrupt and ineffectual.

The hero is Dr. Kishiwada, a brilliant but demented scientist, who creates bizarre mechas, battles the forces of evil, or just mucks about. There are many parodies of B-grade sci-fi movies and of TV. Crazy, slick, and very funny.
