Who would be the most interesting villain in a Daredevil Batman crossover fanfiction?

The Reverse - Flash would be really interesting. He could target both Batman and the Flash. For the Flash, he's a long - time nemesis, but for Batman, he'd be a new and extremely dangerous threat. His ability to manipulate the speed force and time could put Gotham in chaos in ways Batman has never seen before. And he could use his knowledge of the Flash to try and set traps for both heroes.

The Joker would be really interesting. Imagine Deadpool meeting the Joker. Deadpool would be both fascinated and repelled by the Joker's insanity. The Joker, on the other hand, would be intrigued by Deadpool's indestructibility and chaotic nature. It would create a really wild dynamic, with Batman caught in the middle trying to stop both of them from causing too much mayhem.

Ra's al Ghul would be a great choice. He has ties to both the Arrow universe and Batman's world. He could be manipulating events in both Star City and Gotham, forcing Arrow and Batman to team up to stop his grand scheme. His immortality and vast resources would pose a huge challenge for them.

The Riddler could be very interesting. He could create complex riddles that not only test Batman's detective skills but also stump Spiderman. His maniacal love for puzzles could be a great contrast to the more straightforward villains that Spiderman usually faces.

The Joker would be really interesting. Imagine him getting his hands on some of Oscorp's dangerous technology. He could use it to create chaos in both Gotham and New York in ways that neither Batman nor Spiderman have seen before. His unpredictable nature would make it hard for the two heroes to anticipate his moves.

Kingpin would be a very suitable main villain. He has his criminal empire in Hell's Kitchen already, and if he decides to make a move on Gotham, it would bring him into conflict with Batman. His power, wealth, and ruthlessness would make him a formidable foe for the two heroes to face together.

Darkseid is another option. His power and his desire to conquer Earth could bring Batman and Superman together. He could target both Metropolis and Gotham, and his presence would require the two heroes to combine their skills. Batman's strategic mind and Superman's brute strength would be needed to face this powerful foe.

Definitely Daredevil and Iron Man. Iron Man's high - tech gadgets and Daredevil's low - tech but highly effective skills would create an interesting contrast. Also, Daredevil's strong moral code might clash with Iron Man's more pragmatic approach at times. Another interesting interaction could be between Daredevil and Black Widow. They both have a background in fighting crime in the shadows, and their different fighting styles could lead to some cool action scenes.

I think Naruto and Daredevil are the obvious main focuses. But also, Elektra from Daredevil's world could be a great addition. She could have some sort of connection to a female ninja in the Naruto universe, like Sakura. Sakura could learn a thing or two from Elektra's combat style, and Elektra could be intrigued by Sakura's medical ninjutsu. And then there's also Itachi. His complex backstory and powerful abilities would make for a great interaction with Daredevil, especially considering Daredevil's sense of morality and Itachi's own moral dilemmas.

Brainiac could also work well. He is an android with an insatiable thirst for knowledge and a penchant for collecting and destroying planets. In a crossover, he could target Earth, specifically Gotham and Metropolis. His advanced technology would pose a major challenge to both Superman and Batman. Superman's super - powers would be put to the test against Brainiac's powerful defenses, and Batman would need to use his wits to find a weakness in Brainiac's systems, leading to an exciting and complex story.
