In the final episode of Justice League Unlimited (Destroyer), some mysterious guy* appears out of nowhere during the fight between Darkseid and the team of Batman, Superman, and Lex Luthor. Luthor sees him and demands help. This guy takes Luthor to someplace and tells him that what he is about to experience is something only a twelfth level intellect can survive. Luthor says he is overqualified and jumps in and is shown screaming.
Back on earth, Darkseid is about to finish Superman, and Luthor appears out of nowhere and offers Darkseid some mysterious object and says, "I have got all you ever wanted." Darkseid walks to him, touches the object, and then both disappear into thin air with a big energy wave emission. All the attackers from Apokalips return to their world, and boom, the world is saved.
My questions are:
- Who was this mysterious guy who appeared out of nowhere during the battle?
- Where did he take Lex Luthor to?
- What did Luthor experience there?
- How did Luthor survive the experience, whatever it was?
- Why did he choose Luthor of all people?
- What did Luthor offer to Darkseid?
* Actually he makes his first appearance in the penultimate episode of Justice League Unlimited where he tells Luthor that he is a scientist and what Luthor is about to do threatens the past and the present.
