Lonzak's henchmen 
These two henchmen worked for Lonzak, aide to Doctor Chaotica, in the holographic program The Adventures of Captain Proton.

In 2375, Tom Paris and Harry Kim ran the program when photonic lifeforms entered it and started a war against Doctor Chaotica. The henchmen accompanied Lonzak on several occasions and served as guards for Constance Goodheart and later Queen Arachnia. The first henchman assisted in preparing the death ray while the second one was knocked unconscious by Queen Arachnia, portrayed by Kathryn Janeway. ()
