Batman: Arkham - Ranking EVERY Villain Worst To Best

When a supervillain is able to work out his enemy's secret identity through nothing other than sheer intellect, how could they not be near the top of the list? Add that to peak physical condition and a taste for medical experimentation that often borders on psychopathic, and you have Professor Hugo Strange.

One of the key figures behind the scenes of Arkham City, Strange practically has free rein over everyone in the prison, having his TYGER guards round up inmates for his intense psych evaluations under the blissful ignorance of Mayor Quincy Sharp.

Strange's master plan is called 'Protocol 10', and the long and short of it is that it involves killing everyone in Arkham City. Batman makes his way up the archaic Wonder Tower, picking off waves of TYGER guards as he goes. When he gets to the top, Hugo Strange is betrayed by Ra's al Ghul, the real head honcho here, and stabbed through the chest.

Just before he dies, Strange orders the computer to blow up the tower, with the passcode, "Wayne".

If he hadn't met his end when he did, how much damage could the professor have done with Batman's most guarded secret?
