Echo

A minor villain from DC's Silver Age, Echo appeared in the 30th-century setting of Adventure Comics alongside the Legion of Super-Villains, including Saturn Queen, Cosmic King, and Lightning Lord.

Stepping out of the Silver Age in 1967, Echo made their debut in the pages of Adventure Comics, brought to life by the legendary creative partnership of Otto Binder and Curt Swan. With a catalog presence spanning an impressive arc from 1967 all the way to 2020, this DC character has quietly persisted through decades of comics history, sharing pages with heavyweights like Superman, Saturn Queen, Cosmic King, and Lightning Lord. Rare in appearance but touched by collector significance — including one key issue to their name — Echo is exactly the kind of deep-cut discovery that makes digging through DC's Silver Age such a rewarding adventure.
