Atomic Robo v08 - ... and the Savage Sword of Dr. Dinosaur (2015)

What do DR. DINOSAUR, the Lost City of Atvatabar, Majestic 12, MARCONI'S secret Nazi space program in South America (wait, what?!), and missing nuclear weapons have to do with one another?
They're about to transform the face of ATOMIC ROBO'S world forever! Yeah, that's right. Strap yourself in, we're doing the one where "EVERYTHING CHANGES."
