Doug Wiki
Dr. Klotzenstein

Dr. Klotzenstein is an alter ego of Roger Klotz as seen in Doug's imagination. He is one of Quailman's enemies.


Dr. Klotzenstein is the owner and creator of Klotz Foods, a company that manufactures addicting and brainwashing junk food. In Doug Vs. The Klotzoid Zombies, he has brainwashed all of Quailman's friends using Zombie Chips, turning them against him. He also hosts the game show, "Wheel of Snacks". After tricking Quailman into participating in the game show, he attempts to brainwash him and Quaildog and send them, along with the rest of the Klotzoid Zombies, to Klotz Land, a theme park where they will work as his slaves. Quailman and Quaildog are able to escape while he's preoccupied, and then pelt him with beets, which he reveals is his weakness.



  • His name is a portmanteau of Klotz and Frankenstein.
