Batman: Arkham Knight - 10 Big Story Moments Fans Will Debate For Years

3. So... Joker's Blood Can Do What Exactly?

In spite of the fact that this was one of the plot's strongest elements, explanation of how Joker's blood could transform people in such a way was unsatisfactory for a number of reasons. We are led to believe that Joker's blood has the ability to rewrite genetic makeup, turning victim's a ghastly shade of white, dying their hair, and even embodying the rogue's character traits. It's an odd, if not fun addition to the game, but suspension of disbelief can only go so far, and as far as devices go this one was incredibly contrived. As one of Knight's offences this one is notably small in scale, but it didn't stop fans from kicking up a fuss on forums regardless.
