The 0th Biotope is a special IGO Biotope. Unlike the rest of IGO's Biotopes, the 0th Biotope is located in the Gourmet World and its existence is a secret from the world at large. It is located on the Cloud Tree in Gourmet World. Their last assigned mission was either trying to locate or prepare Acacia's Full Course Menu, and preparing for a possible war against the Gourmet Corp.
It is also unusual in that its staff, who number less than 20, are not IGO employees, but are all private citizens who have other professions when not at the Biotope. As revealed by Ichiryu this is done to reduce spies. They are called "the best of the best," and are all chosen by the IGO president, Ichiryu. It is possible that the reason it can't be staffed with IGO employees is because not enough people in the IGO are strong enough to survive in the Gourmet World. This attests to the power of the staff there. More proof of the organization's strength is the fact that they capture and observe Nitro at the Biotope. However, even though they are extremely powerful and not exactly employees of IGO, they still take orders from IGO executives, including Mansam and Ray.
By the end of the events in the Cooking Fest Arc many of their members disappeared, betrayed the organization, were killed or left unconscious, leaving in an unknown status the operations of this Biotope and the majority of its members.
