Dr. Zacchaeus Zimm

Dr. Zacchaeus Zimm is the main antagonist of Max Einstein: The Genius Experiment and Rebels with a Cause. He was later replaced by Viktor von Hinkle.

Personality and Appearance
Dr. Zimm is bald, much like his replacement. He is known for his giggle of glee, where Leo got his giggle from. Not much else is known about his appearance.

Dr. Zimm, like all the other workers for the Corp, is greedy and inconsiderate. He thinks that people should be helping themselves instead of others. He also has a great desire to have Max Einstein, the protagonist, work for the Corp, and build a quantum computer for them. As he said in the third book, that if she does a good job, he will tell her all he knew about her past.

Meeting Max
When Max, who was one at the time, traveled 99 years into the future from 1921, she landed in Dr. Zimm's basement. Dr. Zimm would find her and hire nannies to take care of her, all reporting to him that she had extraordinary abilities for such a young child. Dr. Zimm, who was working for the Corp, realized that she could make a valuable addition to his team, and dropped her off in the stables where the homeless squatted and left as he didn't want to take care of her anymore.

Reunited with Max
Max attended NYU (New York University) unwittingly falling under the supervisation of a Corp agent, named Phillip Stark. Mr. Stark, like all the others, was greedy for money, and when he saw Dr. Zimm's price for Max Einstein, he agreed to become an agent. He got Max "arrested" by the "law" and taken to Little Angels Orphanage, where Max felt socially awkward and attended school that was below her level. Dr. Zimm had planned for Mr. Stark to put Max into the orphanage and leave her there until he would come pick her up. However, the plan failed as the CMI came to her first and took her to Jerusalem, Israel. Because of that, Dr. Zimm questioned Mr. Kennedy, who had been living with her throughout her time in the stables and knew about her encounter with the CMI. Mr. Kennedy was very suspicious as Dr. Zimm had told him more than he should have. So Mr. Kennedy lied to Dr. Zimm, saying that Max, Charl, Isabl, and Mr. Weinstock went to Milwaukee instead of Jerusalem. Dr. Zimm unwittingly believed it, departing from Mr. Kennedy saying that if they don't find Max in Milwaukee, they knew how to find him. However, Ben, who was the benefactor and the boss of the CMI, was a step ahead of Dr. Zimm. He knew that they knew how to find Mr. Kennedy, so he got him moved to an apartment that is currently unknown by the Corp.

Hunt for Max
Eventually, the Corp caught up with the CMI and tracked Max down with an Einstein bobblehead doll which seemed so innocent, but it had a tracker inside, helping the Corp keep track of Max's location, now knowing that she was in the Dominican Republic in Africa. They soon got ahead of the CMI as Yahav was working for the Corp. Dr. Zimm, realizing that he could pursue Max later and replace her job to make a quantum computer with Vihaan and Klaus, ordered Yahav to kidnap them instead, which he obeyed easily as the CMI was busy solving missions and the mayhem in the village and they probably would not have noticed if 2 of their members were missing. Also, the mine manager in the Dominican Republic was on Dr. Zimm's side, but the Corp did not succeed in capturing Max, Klaus, or Vihaan.

To Ireland!
In Rebels with a Cause, the Corp became more powerful than before as they now had Lenard, who was a robot expert tracker. Now that they had Lenard, they could tail Max on her every move. Dr. Zimm came to Ireland, where Max was helping Siobhan to help her clean her village's water. No one was prepared for Dr. Zimm's sudden arrival, and Dr. Zimm knew it. However, Max's quick thinking saved the CMI once again. She served a drink to Lenard as she knew robots did not enjoy water.
