Tesla was an awesome character in Scott's books, but he was also awesome in The Last American Vampire, and in that old TV show Sanctuary, and that got me thinking: In Goliath, Alek shocks Tesla to death. In Sanctuary, he's a vampire with electric-shock powers. In LAV, he's hanging out with a vampire and taking down Rasputin. All of these events seem strangely linked, and it would be awesome to thinks in each series, it was the same Tesla.
My fan theory: When Alek shocked Tesla, he had already gotten Henry (The Last American Vampire) to bite him, and thus, vampire Tesla, did not die. However, Alek did give Tesla his electric powers, which he used in Sanctuary. Yep. 3 different series, 1 Tesla, that's how awesome he is.
