As the topic said. Who are the oldest characters in dc universe?
No cosmic entities or gods such as The Endless, Presence, Anti-Monitor, World Forger, Darkseid etc.
The candidates I can think are as follows
Mordru——older than the universe itself
Ganthet/Guaridans of the Universe——as old as the universe itself
Martian Manhunter——millions of years old
Vandal Savage——thousands of years old
Wonder Woman?(not sure)——thousands of years old per writer's interview
That Green Lantern villain Volthoom was imprisoned by the guardians for 12 billion years before he was released so he’s up there.
He was awake and aware that whole time too. Guardians are dicks.
