Mad Skin, an example of a command core.

When the Bacterians take over planets, they use bio-weapons such as Zelos Forces to grow Bacterian cells on their conquered territories, transforming them into Organic Fortresses. The Organic Fortresses are headquarters where the Bacterians plan their attacks. If the command core of the Organic Fortress is destroyed, then the living planet will revert to its original state.
