Heisenberg

Personality; Heisenberg is a clever and manipulative individual who toys with Ethan throughout the game. Unlike other lords, he recognized that the Mother didn't have any genuine empathy towards her "children" and was only treating them as her servants and lab rats. He is also the only Lord to be against and despise Miranda because of her intent to revive her daughter and he sees Miranda's family as nothing more than experiments. Because of this, he is starting a rebellion secretly and also tried to persuade Ethan Winters to join him.

In spite of his intelligence, Karl is a confrontational and hot-headed man prone to poor impulse control, name-calling and melodramatic behaviour, which can be gathered from his commentary on Ethan's "obstacle course" in the beginning and his speech in general, which often impedes his ability to sustain relationships with the others and is the ultimate reason behind Ethan's refusal to support him, since, while he was engrossed in his emotional rant, Karl quickly revealed his intentions of using Rose as a weapon against Miranda.

Heisenberg and Dimitrescu often don't get along with each other as Dimitrescu called him a child as shown when Heisenberg captured Ethan and both he and Dimitrescu were arguing on who gets to kill Ethan. Heisenberg also said that Dimitrescu has a big ego, which makes him a hypocrite, considering his own narcissism. Heisenberg gets enraged when other people tend to foil his plans as noted when Heisenberg when mutated told Ethan that he should have joined him and also called Chris Redfield a "boulder-punching asshole", referring to an infamous scene from Resident Evil 5, which means that he is somehow aware of Chris' mission in Africa.

Despite being sadistic and ruthless, unlike the other four lords, Heisenberg respects Ethan and is even impressed when Ethan escaped all of his traps. However, once Ethan refuses to aid him in his plan, Karl's attitude almost immediately changes to cold and hostile, as he tosses Ethan into the hole, leaving him at the mercy of one of his creations, though right before doing so, he still presents him with one last chance to accept his offer.

He takes great pride in his "Soldat" units, seeing them as a proof of his superiority over others (even though their design is far from perfect), and has a rather darwinistic outlook on life, believing that "the strong will destroy the weak". Remarkably, Karl is so fixated on killing Miranda not only out of his desire to be free of her influence, but also out of simple grudge that he holds against her for using him as a guinea pig in her experiments. Not only does he not lose this goal after undergoing a radical transformation, but is also the only one of the lords to retain his sanity and intelligence upon mutation, with his arrogance, talkativeness and overconfidence being still in tact.

Appearance; Heisenberg is a tall middle-aged man with long black greying hair, a mustache and beard. He wears a long tattered brown coat with a beige shirt underneath, brown trousers, boots, gloves and a wide-brimmed hat, as well as what seems to be a compass, an old fish scale and a dog tag around his neck. His weapon of choice is a huge custom-made hammer assembled from different mechanisms that he sometimes carries around with him. He also wears old-fashioned sunglasses, and is often seen smoking a cigar.

Once transformed, he assumes many forms thanks to his magnetic powers and an abundance of metal on the battle arena, but mainly stays as a huge robot-looking creature with an elongated "neck", two long arms and caterpillar treads that he rides upon. His deformed face is also visible.
