Hammerhead is the leader of the Cult Gang the Hammerheads. He is a full body exotic conversion, whose appearance is significantly altered to appear more closely that of the Hammerhead sharks that he worships.
As the leader he demands complete obedience and is brutal in his dealings with those not showing complete deference or loyalty. He has been known to rip apart members of his own group, whom he deemed weak or unworthy.
His complete goal is to bring about the great Hammerheads punishment upon mankind. While this somewhat nihilistic ideal is dangerous, Hammerhead is very intelligent and is capable of creating elaborate and masterful plans to achieve his goals.
