Also, we're lacking someone that does heavy weapons or is so heavily augmented that they are no longer able to pass for human -- in short, a tank. This would be the guy that can throw the vampires around and use one as a club on others. There are other possibilities as well, such as a drone pilot-controller type and an investigative specialist that knows how to follow the trails and track the quarry. (Such as Deckard from Blade Runner, who hunted down replicants. In short, a detective type of hunter.)

Just a thought going in.

Also, JonxlatheLion, I am not opposed to a fully robotic character, but I'd like to see some sort of connection to Aspida or some sort of justification as to how he acquired programming that gives him a thorough knowledge of vampires.
