I forgot to mention this before, but I'd say stay away from Graphic Novels.
I agree that Newgrounds is for Flash not just animation.
But to me Graphic novels seem like a cop-out.
You have so much talent as an animator, and it seems like you'd be cheating yourself and newgrounds if you changed to doing a graphic novel series.

Seeing how long Blockhead has been around and how much time/effort it takes to make an episode it makes total sense that you're running into this kind of issue. For me it makes little/no difference if the setting changes/there are new characters introduced like the Weevil or anything along those lines. I think with longer running series' the audience tends to take greater ownership of the characters, and don't like to see them outside of their own interpretation of each one. So i guess I mean Blockhead and the Conscience are the same no matter where they are or who they are with as long as they themselves stay in their character roles. I would totally welcome something new/unexpected as long as the characters don't change.
I totally agree with an earlier post that said the Conscience is better when he is right rather than when he thinks he is. Also, I think my absolute favorite quote from the entire series is when the Conscience says in response to himself: "He asks, not expecting a real answer." From one of the first few episodes. I see the Conscience as sort of representing us, the audience as we might react to these situations. So when the Conscience talks to himself I think it opens up a whole world of opportunities.
I agree with you when you say you like the hyper blockhead best. Some of the best jokes come from his dialog, the way it makes sense to him and to the audience, but it's a delayed response which is a great hook. Actually I think everything that made Kramer from Seinfeld so great is exactly what makes Blockhead great. He creates mayhem without consequence, in fact I'd like to see Blockhead in a situation where he actually benefits despite his total lack of a grasp on reality- like in the Time Squad series! Genius!
