George Davis
In Reality Z-25 31-H, Gwen Davis's father George Davis was a rather narrow-minded businessman.
Shortly after his daughter moved to the Naked Jungle of Buranda, he travelled with her jilted fiancé Dirk to the Jungle to try and force Gwen to return to “civilisation” and go through with their scheduled marriage — at gunpoint if necessary — despite Gwen's insistence that she was already married to Kaza as the “law of the Jungle” reckoned such things, and that Dirk didn't actually care about her, or indeed Mr Davis, only having eyes for his company.

Some years later, Gwenna was speaking with Jung-La and said that her marriage to Kaza drove the both of them apart but when she contacted her mother with the hope of patching things up with him, she learned that he was already dead of a heart attack. (COMIC: Situation on Earth-N)
