Still grows up to dress up like Batman but just regularly breaks into his dad's house in the middle of the night and beats him up in his sleep, goes around beating up other abusive or deadbeat dads who never pay child support, helps single moms find gainful employment and other community resources like food banks. Kills landlords who try to evict them.

Based Batman.

One step further: they’re just divorced but he tells everyone they’re dead

Thomas Wayne loses half his fortune in the divorce, and keeps losing more in child support. His depression keeps growing, he can't bring enough in. He can't do anything.

Alfred retires. There's no place for him anymore. He later hears about his old boss eating the double barrel. He attends the funeral , quietly wishing the man had just asked him. He would've been kinder.

Martha lives a lavish lifestyle, leaving Bruce to the side. He gets a common man's education, common work. The death of his father still haunts him, that final moment when the young boy peaked into the casket burned into his mind.

He decides no one should go through this. There has to be a better way. He doesn't have much, can barely keep food on the table for just himself, but he stays up late, working. Learning. Getting better.

One morning, he goes into the sanitation department where he works, and informs them he's quitting at the end of the day. He has a new dream, one that's going to take all his time.

A month later, his old coworkers are out on the job, and what do they see? Bruce Wayne, Marriage Councilor.

He beats the couples until they agree to remain together. He dies penniless, alone, and destitute, having never succeeded.
