Bane and Killer croc.
Sharp mind and strong body. Despite what you may think, it's not the drugs that makes him like a crocodile... rather it helps him stay more "human". The drug was developed to counter act the virus he has which is slowly transforming him. At the same time, his strength is dramatically increased as a side effect... not so bad of a side effect except that now he must rely on the drug or else suffer extreme weakness and further transformation into his cold-blooded like form.
