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 2
Crowd scenes are both a pain in the ass to draw, and so much fun. They require tons and tons of detail, but they also allow one to hide lots of crap in the background. Captain Tacolicious' The Pinnacle and V (from "V for Vendetta") are visibile in this panel.
Panel 3
Here we can see Crow T. Robot and Tom Servo rather plainly. Those hands coming from behind the torch bearer belong to Mike Nelson, the superior host from "Mystery Science Theatre 3000."
Panel 7
Notice how huge Hitler's head is. I can come up with justifications thereof, fish-eye lens and all that, but the real reason I drew it like th at is because it's a lot funnier than it would be otherwise.
Lots of crap in this crowd. First there's and old guy and a vaguely cylon like robot wearing Mork and Mindy shirts. Next to them is some guy in a Superman One Million t-shirt. Not to over-explain, but Superman One Million is a hypothetical future version of the man of steel that appeared in a crossover from the late nineties. It was better than other crossovers, however, because most of it was written by Grant Morrison. Next to him is a fat lady in a Captain American moomoo. Next to her is Neo.
I think I really overdid it with this panel.
Above that you can see the Toadstool Retainer, Robin Hood in sunglasses and Alan Moore holding a sign that reads "John 3^16."
