Deucalion it seems, like his other fictional counterparts, has a dark and murderous past. An example of this is the fact that he murdered Helios's first wife, Elizabeth, when Helios was still Frankenstein (not Helios's New Race wives, Erikas 1-5). He desires redemption and believes it is his destiny/duty to kill his creator. The irony of this is that he, like the others of his "race", cannot kill Helios personally, although he lacks the restrictions on killing that Helios has placed in later creations and can therefore kill anyone else, whether of the Old Race or New Race, without complications.
