Hitler's back. A mad scientist thought he could reform him; make Hitler a productive member of our future society. He was wrong. Now, the only thing standing between mankind and total oblivion is Albert Einstein. Einstein has hand picked the greatest minds in history to face off against this great evil. But who will prevail the latest iteration of The Third Reich? Or the Heroes of Science!

Annotations and commentary

Panel 4
For some reason the Heroes of Science always find themselves in abandoned structures which, inexplicably always have intact, but inert, computer rooms. It's sort-of like the "I woulda gotten away with it, if it wasn't for those meddling kids!" plot device from "Scooby Doo."
Panel 5
I started off "Da Vinci's Cypher" with Leonardo explaining how his newly-invented beard, hiding spot works. This was to remind the reader about Leonardo's most-commonly used special ability. I'm all about economical writing.
Panel 8
I know, I'm going to the "panel with only a sound effect in it" well too often in this chapter. I won't do it again. I promise.
