Okay, let's see if this brings back the group:

Okay, we all know this guy, right?

For those of you who don't, he's the Borad, dictator of Kharfel, but cast to Earth by the Sixth Doctor. He's a generally calm but vain and misanthropic genius who, due to his disfigurement, prefers to do most of his work in hiding.

Let's say he and Davros were working on a project together; how do you think they would interact with each other?

Davros absolutely betrays him once he has outlived his usefulness. This probably leads into Davros's own betrayal and apparent extermination by the Daleks, which he will protest vociferously without seeing any sort of hypocrisy in his arguments.

Until that point though, they'd probably get along pretty ok. There would be the inevitable clash of egos every now and then, but Davros can be charming and personable when he wants to be. (AUDIO: The Juggernauts, TV: Magician's Apprentice/Witch's Familiar) He just doesn't usually want to be. (Basically anything else that Davros has ever been in)
