The Cosmos is how the BioWarriors refer to the human host body. Inside the Cosmos, BioWarriors represent cells, and their body parts represent cell components, which retain the real-life functions of their biological counterparts.

High above it all, between the pulsing twin hemispheres of the host brain, is the Council of the Mind. Here the eight members of the Council, the wizard-like supreme neuron cells, receive the ethereal thoughts of the brain and translate them into messages that can be relayed by Messenger Nerve Cells to the rest of the Cosmos.

During normal cellular operation, BioWarriors of the same type will group together as a follice. This tightly knit network provides for quick and easy communication and deployment.

Lymph nodes located throughout the Cosmos serve as the base of operations for the B-cell army.
