The Forevers #1 (July 1976)
The Forevers are a subfaction of the Maximals, but they live forever. There are many ways a Forever can die, including the Rite of Sacrificing a Forever, if he or she has a disease like Cosmic Rust. They were formerly led by Chronox, the ox-transformer who gave his life to defeat the former Extincteviant leader Uranix. Now they are led by Zurabbit, in their base at Po-Lar. They comprise of rat-transformer Ikarion, cat-transformer Sersa, and hundreds of others, many of whom first appeared in The Forevers #1 (July 1976).
