However, they offer force fields and protection for many Perios against more aggressive clans such as their neighbors the Halogens. They can also provide light when needed. All of the Aerogens are vapors , which means they are able to travel very fast across Perioland and on Earth. One of the Aerogens, Rad, is a radical (radioactive). The family sign of the Aerogens is 0.
