In this fanfiction, the TMNT might escape by first observing their captors' routines. If the Shredder has minions guarding them, they could wait for a shift change or a moment of inattention. Donatello might be able to hack into any security systems if there are any. Also, they could use their knowledge of the sewers to find a way out. Maybe there's a hidden passage that the Shredder doesn't know about. And of course, their ninja skills would come in handy for sneaking past guards and making a quick getaway.
When writing about Shredder in a TMNT fanfic, you can really play with his character. You can give him new motives or goals that are different from the original. For example, he could be on a quest for a powerful artifact that he believes will make him invincible. His fighting style can be described in great detail, highlighting his skill and ruthlessness. You can also explore his weaknesses, whether they are physical or psychological, which could add more layers to his character and make the story more interesting.

For instance, perhaps the Turtles have to rely on each other more than ever in this future - based story, and their bonds are tested in ways that are different from the regular TMNT stories.
Well, it could be about the Turtles facing a new and powerful enemy that they've never encountered before.

It's hard to say. Batman has his intelligence, gadgets, and martial arts skills. But the Shredder is a formidable ninja with his own set of deadly weapons and a whole clan of ninjas at his command. However, if Batman can use his environment and his gadgets effectively, he might have the upper hand.
