If Harry is raised by the Joker in fanfiction, it's likely that he'd have a very different set of skills and values. He'd probably be extremely good at manipulation and deceiving others, having learned from the master of chaos himself. His view of the world would be tinted with the Joker's nihilism. For example, he might not see the point in heroism or justice as we know it. Instead, he'd be more focused on causing disorder and having a laugh at others' expense. His appearance might also be affected, perhaps taking on some of the Joker's flamboyant and menacing style.
