In this continuity, Gim Allon was known as Leviathan and was from Mars instead of Earth.
While the team struggles against the massive invasion fleet, Superboy, Element Lad, Sun Boy and Colossal Boy take the fight to Khundia (the Khund homeworld), where they learn that the Khund warlord Garlak is being telepathically manipulated by an outside force -- which they trace back to Weber’s World.
Legion deputy leader Element Lad and Science Police liaison Shvaughn Erin became suspicious of the fake Violet when Yera, wearing Violet's form, suddenly fell in love with Colossal Boy, who harbored an unrequited crush on the real Violet for years.
