Interplanetary Special Investigations Service. United States operation involved with alien contact. Current plans call for an amalgamation with similar European, Japanese and Russian agencies under the aegis of the United Nations. At the moment, the organization has extraterritorial powers in several countries and alliances with many similar organizations.
While the organization has several bases and agents working for it, it maintains one active super team, based generally in the Johnson Space Center in Houston, Texas. The current active membership of this team is:
Dreamscape
Templar
Webslinger
Riptide
Green
Lantern V
Radiance
Symbiote
Anthem is a noted hero who has been active for over 20 years. He was one of the first recruited into ISIS and he is generally on call by that agency whenever he is needed. He often is sent independently to investigate alien appearances on Earth.
Dr. Alphonse Stygious was once the notorious Dr. Styx. He paid his debt to society and retired, and now acts as the ISIS Team's general factotum, supplying technical aid when necessary and occasionally bringing out the Styxbot, a large mecha equipped with high defenses and a number of capture weapons.
