A more unorthodox plan could be for Oracle to spread false information about a powerful new weapon that only Robin knows how to operate. This would make Luthor believe that Robin is more valuable alive than dead. Then, while Luthor is distracted trying to figure out how to use Robin to get this weapon, the heroes could stage a rescue. They could also try to turn one of Luthor's minions against him. Offer the minion a deal in exchange for information on Robin's whereabouts.
Robin might initially be defiant. He's a trained fighter and detective, so he'd likely try to gather as much information as he can about his surroundings. He could be looking for any weaknesses in Lex Luthor's security setup or trying to figure out what Luthor's endgame is.
Perhaps Gray and Erza lead a search party. Gray could use his ice - make magic to freeze any obstacles in their way while Erza, with her many armors and combat skills, could fight off the kidnappers. They might also get some help from the other guild members like Wendy, who could heal Natsu if he's been injured during the kidnapping and torture.
It could be Nightwing. He was once Robin himself and has a special connection to the current Robin. Nightwing might hear about the kidnapping and step in to save Robin, using his own unique fighting style and experience.
It can be disrespectful to the original source material and the intentions of the creators. The character of Lex Luthor has complex traits that should be explored in more meaningful ways.
Superboy could use his super - strength to break free from whatever physical restraints Lex Luthor has put on him. If he's chained up, he could simply snap the chains. Then he could use his super - speed to run out of the facility before Lex Luthor's guards could react.
One interesting storyline could be Lex Luthor secretly funding a group of meta - humans to create chaos and then swoop in as a'savior' to gain public favor. This would play into his manipulative nature.
Yes, Lex Luthor is often depicted as bald in the comics.
One of the best Lex Luthor stories is 'Lex Luthor: Man of Steel'. In this story, it delves deep into his complex psyche. It shows his envy and hatred for Superman, not just as a being with superpowers but as a symbol of hope that he can't tolerate. Another great one is in 'Action Comics' where his devious plans to take down Superman are meticulously crafted, highlighting his brilliant yet twisted mind.
One great Lex Luthor OC fanfiction is 'The Luthor's New Ally'. It offers a fresh take on Lex's character by introducing an original character who challenges his views in unexpected ways.
The concept of morality often comes up. Lex is often seen as a morally gray character. In crossovers, this is contrasted with the moral compasses of the characters in the other universe. For instance, in a crossover with a more utopian - like universe, his self - serving actions are highlighted even more. Also, exploration of new technologies or powers is common. If he crosses into a world with magic, he might try to understand and harness it for his own purposes.
