What if Sauron obtains The One Ring but Eren Jaeger joined the side of Men in Lord of The Rings?
Pippin drops the ring (somehow) and Sauron gets it. He gets reformed and is ready to lay siege to the world of men
Eru sends Eren Jaeger to help fight against him. Eren has all his end of series titan abilities.
If the founder is too much (actually yeah Idk what Sauron could ever do to that) then in round 2 Eren has all the abilities except for the founder 1200 foot giant body ability and creating past titan shifters.
How would it go?
