Bio: Coming to the Fortress of Solitude on Superman's birthday,
Mongul tricked Superman into opening the canister, believing it was a
gift from some alien planet. What was inside was the Black
Mercy, a powerful animal that had the ability to put the person
it's attached to in a dream-induced state, in which their
ultimate dream becomes reality.
Despite a heavy resistance from Wonder Woman, Mongul didn't
truly go down until Superman broke free from his dream.
With Mongul about to deliver the final blow to Superman,
Wonder Woman broke the Black Mercy off of Batman and flung it
onto Mongul, trapping him in his own world, where he alone
ruled.
