He may be expected to use his powers for different purposes in each world. There could be a power struggle within the wizarding world as some might want to use Harry for their own gain, thinking he has access to Crowley's knowledge and abilities.

Well, perhaps Crowley would use his dark powers to protect Harry in a rather unorthodox way.

He'd probably be more morally ambiguous. Growing up as Crowley's son, he might not have the same clear - cut sense of right and wrong as the original Harry. He could be more cunning and less hesitant to use underhanded tactics if necessary.
A plot twist could be related to Fem Harry Potter's magical abilities. Since she is raised by Crowley, she might develop some unique magical skills that are a blend of wizarding magic and Crowley's own brand of 'power'.

When these enemies discover her existence, they target her to get back at Crowley, putting her in great danger and forcing her to rely on skills and knowledge she has learned from Crowley to survive.

He could face a lot of inner turmoil as he tries to decide whether to embrace his dark heritage or fight against it.
In this fanfiction, perhaps Harry's identity as the Joker's son makes him an outcast in the wizarding world.
