Senior Fanboy Killer
1) The Joker. The only person who has consistently been able to get inside the mind of the Bat. He is either a super-psychotic criminal, or a super-brilliant criminal whose brilliance is misinterpreted as madness (that theory was once explored in a comic). Either way, he is brilliant enough to be the Bat's cerebral antagonist. In a way he represents the madness that drives Bruce Wayne, and in many ways the two share the same demons! It is just that Bruce is more organized and less chaotic, but they are both stark raving mad! No wonder they always gravitate towards each other.
2) Ras Al Ghul. A man that could easily be what Bruce Wayne will be in the future. He presents the constant temptation that the Bat has to face .....the ability to actually stop crime and solve things by using his great wealth and influence. Think of it, Ras wants to do good ....it is just that his good means killing most of Earth's human population in order to cleanse it. If Batman ever suffered a breakdown, he could easily become someone like Ras (which might be why Ras always admires the Bat and wants him to be his heir ....he recognizes the potential in the Bat). You also have to realize that Batman has been tempted by the Lazarus pits in the past, and currently has a Lazarus pit in the Bat cave. Imagine what will happen when a Batman who is 50 years old and not as fast as he was before looks at that pit ......and the temptation of being ever youthful comes. It is a slippery slope Batman will always face, and Ras is basically a Batman who went too far.
3) Hush. Another cerebral antagonist to the Bat protagonist. He is also what the Bat could become if he had taken another path after the demise of his parents. Rich, super-clever, and willing to do anything to achieve his objectives. Also able to use prep to weave a very intricate plan that comes together in the end. Shhhh .....
4) The Red Hood. Once again another representation of what the Bat could do if he stopped holding back. Imagine it, no need to take people to Arkham or Blackgate (only for them to escape a few weeks later, or get released by a corrupt legal system). Imagine never having to hold back ....which would make Batman into a Lady Shiva with gadgets! Imagine never having to worry about the ethics of taking over the financial system, or taking down the Government (think of what the Bat could have done when Lex was president ....the guy was infiltrating the White House like it was a joke). Batman holds back too much, and the Red Hood represents the temptation of finally NOT doing that. Of Batman deciding to really let go.
5) The criminal that shot his parents. Simply for the question on whether that perp created the Batman, or if the Batman always existed (some evil dark seed within the young Bruce Wayne) and he only awakened it. What would have happened if the parents had never been shot? Would Bruce have become a serial killer instead? His level of dedication (which is actually controlled madness and zealotry) means he would never have been 'normal.'
Maybe that criminal did the world a favor!
Imagine the evil potential of a Bruce Wayne without a dedicated goal?
Or, even if you believe Bruce would still have been good (I do not, I think Bruce is inherently evil ....it is just that, for now, he targets evil doers ...think of it ....the guy had a Sinestro ring choose him in the entire sector!!!!!! Why would a ring attracted to fear and evil select a HUMAN) .....anyways, even if you believe Bruce would still have been good, had the parents not died he would not have been Batman. Think about all the terrorist attacks and alien attacks and metahuman attacks that would have occured, without a Batman to stop them?
For one, Gotham city would have been destroyed many times over (imagine the No Man's Land event without a Batman)?
That makes the nameless faceless criminal (even though some writers have tried to hint it is so or so) the most important criminal on my list, even if he is at number 5.
That is because that criminal represents random potential and probable choice ....probability and self-questioning.
What if?
My favorite villain of them all!
