For Series 4 (1979), Mego introduced its first line of figures exclusive to the Micronauts: the Aliens. Antron was a six-limbed figure with an exposed glow-in-the-dark brain and weapons for extremities. His purple body was accented by blue feet and wrist cuffs, while red weapons (a blaster, a hook, a ring and a "hive" weapon) were attached to the cuffs by the 5mm system.
Like the other Series 4 Aliens, Antron was reissued in Series 5 with a light green brain. Unlike Repto and Membros, however, Antron's original brain was dark green. The later brain had improved light retention for the glow-in-the-dark feature.
