So new idea that randomly sprung forth!
Madara Uchiha is sent to Middle Earth.
Have fun with that, that's all I'm saying for this idea.
HAHAHAHAHA JK!
So it probably can happen some different ways:
Option 1: Some god or something sends him there so he can redeem himself.
Option 2: The Allied Shinobi Forces use an experimental seal to send his remains somewhere so he can't be reanimated anymore.
Option 3: Very funny because of it: jutsu gone wrong. uchiha are basically labeled as jutsu masters due to their sharingan, so it's funny for madara to accidentally perform a jutsu wrong.
Now onto what Madara will do, will he:
Join the Fellowship's efforts in defeating Sauron?
Perhaps remain neutral until due to the actions of both sides gets him involved?
Maybe even join Sauron for some reason, per say, a way to get home? (for options 2 and 3).
Mere suggestions:
Maybe someone gets sent with him? Hashirama? Naruto? Sasuke? Maybe even someone completely random like... Shikaku?
What if someone else had come from the Elemental Nations to Middle Earth before them? Maybe a Senju? A Uchiha? Maybe even... an Uzumaki?
Madara gets a cool-ass sword (not a sword belonging to anyone like Aragon or Gandalf) that somehow ties to an ancient prophecy told ages ago, maybe when Sauron first began his attempt to take over Middle Earth.
Places like Erebor, Dale, and Mirkwood are visited or at least mentioned at some point.
Have an OC in it! Having OC's in fanfics (as long as they don't become OP like instantly) will spice it up and make it more interesting!
Ja ne~
