Ganglios

Ganglios made their DC Universe debut in 1986's Who's Who: The Definitive Directory of the DC Universe — which means this character arrived fully codified, introduced to readers as an established piece of the cosmic tapestry from the very start. Sharing pages across the decades with Legion-adjacent figures like Tellus, Timber Wolf, Ayla Ranzz, and Brin Londo, Ganglios orbits one of DC's most beloved far-future mythologies, appearing across Legion of Super-Heroes and Adventure Comics in a catalog run that stretches impressively into 2016. With 21 appearances, this is a character for the dedicated DC explorer — the kind of deep-cut discovery that rewards readers who love the rich, sprawling corners of the Legion's universe.
