Bio: Dr. Chumwell was a dentist that She-Hulk brought one of her clients to. Her client had recently had dental work done by one Dr. Bob Doom (fifth cousin to super villain Doctor Doom) and soon after he started receiving AM radio transmissions from the filling Doom had put in. Dr. Chumwell found a device in the client's mouth and removed it. She-Hulk asked if he would be willing to sign an affidavit as to what he found in the tooth and re responded that it would be his professional obligation. This would help in the lawsuit that She-Hulk was going to bring about on Doom for implanting the device in her patient's mouth.
