Zach has a very thin build and very pale skin; he is barely taller than Chris. He has black, shiny hair and green eyes. He also has a small, black goatee. He typically wears a black turtleneck sweater, gray slacks, and black pointed shoes. His head is triangular in shape.


Zach is extremely arrogant, stubborn, and self-centered; he is also extremely narcissistic, often referring to himself as "the world's greatest inventor/mind," even programming his computers to refer to him (Zach) as "my greatness," despite the fact that his inventions often fail and Aviva's do not, and is even shown to have his own perfume. (Polar Bears Don't Dance) Zach is portrayed more comically than the other villains; his screams are girlish, he constantly trips and falls, and he has to deal with the literal mindedness of his Zachbots. He is also somewhat sadistic, as he has been shown to resort to outright killing the Kratt brothers, such as when he lured them into a deadly arctic storm (Polar Bears Don't Dance), and drowning them (Mystery of the Weird Looking Walrus and Creature Power Challenge). He has an enormous ego, one that nearly rivals, if not outright surpasses, that of Aviva's and/or Donita Donata's. His arrogance is not unfounded, however, as he actually is a pretty good inventor, since he is very wealthy. Despite this, he is also a coward. Due to his dislike of the Wild Kratts and their interferences, he usually refers to them as "Wild Rats".


Zach's plots typically involve collecting animals and turning them into robots, but not all of Zach's plots deal directly with animals, rather the animals simply just get in the way. These plots include stealing inventions and trying to win competitions by cheating.

He has professional robotics and engineering skills, with highly advanced tools and weaponry. His inventions are able to display holograms, laser-like projections, hovering capabilities, and/or being able to camouflage. He has an army of robot minions known as "Zachbots." He makes his robots do the dirty work, while he thinks up the plans.

Due to his immense wealth, Zach possesses various means of transportation; more so than the other villains. His primary means of travel by air are a V-shaped jet, a large, gray cargo propeller plane, and a large, gray cargo jet. To travel by water, he either uses a steel plated yacht, or a gray submarine. All made to his designs, and they work pretty well.



(After a Draco Lizard lands on his face) "Mommy… GET IT OFF!  Its icky feet are scratchy!
—Zach, Flight of the Draco
First, you'll watch me eat your precious platycat egg omelette! Then, I'll take care of you!
—Zach to a miniaturized Chris, Platypus Cafe
I said tea, not tree!"
