Davis is a millionaire who takes over ownership of the UFO Center where Max Evans works. On a number of occasions, he claims to have been abducted by aliens. He tells Maria DeLuca that, in essence, his mind would go blank and he would awaken a few days later lacking knowledge of where he had been or what he had been doing. In reality, his body was being used as a vessel by aliens to come to Earth. He later tries to develop a device that will "open a part of his brain" that he believes contains memories of where he had been taken. This device malfunctions and the resulting shock reveals previously unknown memories to him, which leaves him confused and afraid. After this happens, he takes Max Evans, Tess Harding, Liz Parker, Maria, her mother and her cousin hostage. Max is able to heal the damage to part of Brody's brain using his healing power, while Michael Guerin and Isabel Evans hold up the FBI outside. Brody is able to elude charges related to the hostage situation, as he is made to forget what happened.
He has a daughter who is very ill and needs a bone marrow transplant, but Max heals her while she is in the hospital.
