One possibility is that Thomas Wayne Batman comes from an alternate timeline. He meets Bruce Wayne in the current timeline and shows him a different way of approaching crime - fighting. Maybe he has more brutal methods, which causes Bruce to question his own more restrained approach. They could then learn from each other and create a new, more effective Batman strategy for Bruce's Gotham.
One possible plot could be that Thomas Wayne somehow time - travels to the present where Bruce Wayne is Batman. Thomas could initially be shocked at how Bruce has turned out, but then come to understand his motives. He might offer some old - fashioned wisdom that helps Bruce in his fight against crime.
The dynamic could be complex. Thomas might be both proud and worried seeing Bruce as Batman. Proud that his son is carrying on the legacy, but worried about the dangers. He could be overprotective at first.
Well, in this fanfiction, there could be an epic showdown against a common enemy. The Justice League might initially be skeptical of Bruce Wayne's methods, but then they come to respect his strategic mind.
Perhaps they start off as rivals at first. Bruce might be a bit suspicious of Barry's powers and his more light - hearted approach. But as they get to know each other better, they realize they can learn a great deal from one another. Barry could teach Bruce to loosen up a bit, while Bruce could show Barry how to be more strategic in his superhero work.
Well, they might start by comparing their high - tech gadgets. Tony would show off his Iron Man suit with all its amazing features, while Bruce would talk about the tech in his Batmobile and other gear. Then, they could end up working together on a project to fight a common enemy, combining Stark's genius in energy and robotics with Wayne's skills in detective work and combat strategy.
In such a fanfiction, they might start by sizing each other up. Bruce would be intrigued by Tony's high - tech gadgets and playboy lifestyle, while Tony would be curious about Bruce's dual identity and his more brooding nature. They could end up collaborating on a project, perhaps something to do with improving Gotham's infrastructure using Stark technology.
One reason could be that Bruce Wayne never had the traumatic event that led him to become Batman in the original story. Maybe his parents' death was prevented somehow, so he never felt the need for vengeance and justice in that extreme way.
One possible scenario could be a time - travel or alternate universe situation. Thomas Wayne might be shocked to see Damian, his grandson, considering his own early death in the normal Batman timeline. He could initially be skeptical or even a bit hostile, thinking Damian is some sort of threat. But as they start to communicate, Damian could show his skills and determination, and Thomas might start to see the family resemblance not just in looks but in spirit.
The encounter could be filled with tension. Bruce might be angry at first, blaming Thomas for leaving him so early in life. But as they talk, they start to understand each other better. Thomas could share his own hopes and dreams for Gotham that he never got to fulfill, and Bruce could see a new side of his father. The description could include details of their body language, like Bruce clenching his fists at first and then gradually relaxing as they talk.
One interesting scenario could be Thomas Wayne seeing Damian's combat skills and being both proud and a bit shocked. After all, Thomas may not have expected such a young and fierce fighter in the family. Another could be them having a deep conversation about family values, with Damian learning from Thomas about the Wayne legacy from its very origin.
