| Synopsis | At Legion tryouts, Infectious Lass infects the Legion with a virus that swaps the Legionnaires' powers and some of their physical attributes with one another, just as a Khundian advance force attacks. When the Legion surrenders, the Khundians apply restraints to each of them based on their research on the Legion, but since the Legionnaires have had their powers scrambled, they are able to escape. Infectious Lass stirkes the Khundians with stomach flu and they retreat. The Legion offers Infectious Lass membership, but she declines in order to sharpen her abilities and offers to serve as a substitute Legionnaire if needed. |
