Doc Leopold was always known as a nut. He was that guy who would wander up and down the fish isle at Petsmart till it was time to close. Little did the citizens of Sarasota know that he was planning to conquer world with a fish army. Studying the cliff notes of Sun Tsu, Patton and Napoleon his goal was to rule southern Florida with an iron fin. Like all great generals, he knew the first step is creating an army is to transform yourself into a giant fish.
With his mutagen fluid ZAAT, he fused himself with the DNA of a walking catfish, which was a lateral move in the looks department.
Dr. Z handles a bit differently than "The Creature" and "The Horror" as he is a summoner-type and doesn't deal damage directly. The key to playing Dr. Z is to stay at range and summon waves of predatory fish to swarm your opponent. The "sargassum haze" spell will slow an opponent allowing Z to call even more destructive aquatic friends to plan revenge with. Though it takes considerable time to charge, his "megalodon crush" is one of the hardest hitting moves in the game.
