Robo

An old Hayato (the original Getter 2 pilot) leads the Saotome Research Facility, which has developed the Getter Robo Hien to combat a new force which threatens the Earth: large plantlike monsters.

The year is 1938 and a vril weapon is being developed that will rival even Tesla's lightning weapon designs! Cue Atomic Robo, Jack Tarot, secret government agencies, moon men, magical arctic circle elves, jetlagged aliens, elderly rights activists, youngling laborers, and the manifestation of human hope to help save the day!

The Trial of Atomic Robo
Objection! Overruled! Gripping courtroom drama ripped from the headlines! It's the trial of the century when a dinosaur sues a robot. Special guest star: explosions! Names have been changed to protect the innocent.

It's 1951. The Pacific Theater of World War II ended six years ago, but the fighting never stopped. Pirates, warlords, and mercenaries jockey for the arms, ammo, and airframes left by the Japanese and American Navies.
And in the middle of it the rogue Japanese military unit CHOKAITEN emerges from the shadows of history. They are on the verge of accomplishing their top secret mission to unleash a devastating super weapon that will sink the North American continent.
Only ATOMIC ROBO and the FLYING SHE-DEVILS stand in their way!

An invading vampire dimension. A giant mutant monster. A probably not time traveling but definitely psychotic dinosaur. An anomalous entity beyond the ken of mortal science.
What do the all have in common? NOTHING! But they make up the business week of sci-fi madness in Atomic Robo's long life.

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."

A true Lovecraftian horror rampages through New York City. Armed with nothing but Charles Forst and a pair of Tesla-built Lightning Guns, Atomic Robo must stop the Shadow from Beyond Time before it swallows the world in darkness - forever!
