I completely agree with your villains. I was thinking hightekvagabond for sure too for obvious reasons. I think he would enjoy that as well. I think superhappytime might make a good villain too. He just seems like the type.

java_fiend is a total sweetheart and would make a good hero. But I know he has some villain in him as well, just lurking beneath the surface (read his response to my comment on this thread to see what I mean).

hug_machine makes me think hero too. She's just so sweet! I agree with both your good nods as well.
