When members of the Legion of Super-Heroes were falsely imprisoned on Takron-Galtos. Two members of the team would come up with a way to rescue them. Aware that there would be massive backlash from the United Planets if they attempted to interfere with their incarceration both Chameleon Boy and the original Invisible Kid Lyle Norg created the Legion Espionage Squad. They were so successful in the original liberation and restitution of the incarcerated Legionnaires that it was decided to keep the unit active in a "as needed" basis.
Although originally formed as a secret resistance group it would be a part of unwrapping plots against the Legion over the years. In theory it is a secretive sub-team within the Legion and only the Legion team leader at the time would be allowed access to the meetings as decided by Chameleon Boy the acting Espionage leader. Specific recruits from the Legion would be included on missions depending on the needs of the mission. The Espionage Squad would undertake missions the Legion of Super-Heroes were not authorized to be involved in.
Chameleon Boy heads the Espionage Squad on one occasion recruiting Timber Wolf and Shrinking Violet to head with him to the Khund homeworld Khundia to accomplish some reconnaissance. Unbeknownst to acting Legion leader Lightning Lad. However Chameleon Boy's actions go awry as they crash land on Khundia soon caught up in a battle in the Khundian Arena's. UP frowns against invading a Khund planet forcing Lighting Lad to forbid any of the Earth bound Legionnaires to help rescue the stranded team.
Saturn Girl along with a small crew of other Legion members had to form a small rescue team to go in and save their teammates. They're plan almost a success they are shot and crash land onto a small frozen asteroid. The Legion Flight Rings now frozen and useless there was no way for the members to communicate or be found. Fortunately Dawnstar who was begged by Light Lass to help find them did discover their location and rescued them from likely death.
