In Adventure Comics #339, one of the members, Beast Boy, who had been shunned by Lallorian society, flees to a jungle planet, Vorn. There he leads the animals on the planet in a revolt against humans. He dies saving a little girl from an attack by one of the animals. He is buried on Shanghalla, the memorial planet.
The Heroes of Lallor help the Legion out several times against the Fatal Five and Darkseid.
Duplicate Boy and Shrinking Violet break up after Imskian rebels kidnap her and replace her in the Legion with a Durlan named Yera. Violet confronts Duplicate Boy for uncovering the imposter via x-ray and failing to rescue her.
The Heroes of Lallor make a single appearance in post-Zero Hour Legion continuity. In Legionnaires #49 (June 1997), Beast Boy, Gas Girl, and Splitter appear in a single panel, being told they cannot help the Legion as they are needed on Lallor. Evolvo had previously been established as a member of the Workforce.
