Who would be the most interesting villain in Loki and the Doctor fan fiction?

One idea could be that Loki and the Doctor team up to stop a time - traveling villain who is trying to rewrite history for their own evil purposes. Loki's trickery and the Doctor's knowledge of time could make for an exciting adventure.

The Joker could be a really interesting villain in this fan fiction. He could somehow find his way to Metropolis and start causing chaos. His insanity and unpredictability would be a challenge for both Red Hood, who has a history with him, and Supergirl, who has never faced such a deranged foe. The Joker could also try to drive a wedge between them to make the situation more difficult.

In Loki redemption fan fiction, aside from Thor, there could be new original characters created just for the fan fic. These characters might be the ones who first show Loki kindness when everyone else doubts him. They could be ordinary Asgardians or even outcasts like Loki himself. Their friendship or relationship with Loki can play a significant role in his redemption. And of course, Frigga is also a common character paired with Loki. Her love for him can be a strong motivation for his redemption.

It could be the Daleks. They are a classic Doctor Who villain. They might see the meeting of two Doctors as a threat to their plans for universal domination and try to stop it.

Reverse - Flash could be really interesting. He could manipulate time in ways that not only affect Flash but also Supergirl. For example, he could go back in time and prevent Supergirl from arriving on Earth, which would change the whole timeline. Flash would then have to convince her to come to Earth again while also dealing with Reverse - Flash.

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.

The Reverse Flash could be an exciting villain in a Supergirl Arrow crossover. His ability to move at super - speeds would make him a formidable opponent for Supergirl. He could also mess with Arrow's timeline, creating chaos in both their worlds. Imagine him going back in time to prevent Supergirl from arriving on Earth or changing events that led to Arrow becoming a vigilante. His manipulative nature and his connection to the Speed Force would bring a whole new level of complexity to the crossover story.

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.

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.

Ra's al Ghul would be a fascinating villain in a crossover. He has a global view of crime and destruction, and his Lazarus Pit gives him a certain immortality. His plans could involve both Hell's Kitchen and Gotham in some grand scheme. Daredevil would be out of his depth dealing with Ra's al Ghul's long - term, world - changing plans, and Batman would have to bring Daredevil up to speed while also trying to stop Ra's al Ghul's latest plot.
