Doctor Bob Doom

Bob Doom is the fifth cousin of Doctor Doom, who is a dentist. No, I am not making this up.
History
As mentioned before, Robert Doom is Doctor Doom's fifth cousin. Unlike Doom, Bob lives in America and has a job as a dentist. He resented and envied Doctor Doom. So, he hatched his own evil plan: after studying weapon technology, robotics and mechanics, he created "neuro-transcivers", miniature devices that allow him to control the nervous system of the victim. He placed them in his wealthy clients' fillings. However, one of the clients accidentally damaged his neuro-transceiver and turned into a radio receiver. Thinking this was simply malpractice, the client sued Bob with Jennifer Walters (She-Hulk) as his lawyer. However, Jennifer found out the truth. She-Hulk easily defeated him even biting his adamantium drill. He is seen later having gone straight and wished She-Hulk a happy birthday.
