Next, they tried their Bio-Mecha Monsters: Terrifying half machine/half organic abominations created by their Nazi scientists. They unleashed hordes and hordes of them against Frankenstein, to no avail. Frankenstein literally slaughtered them with impunity.
They radio'd back to their home planet, Mars, and had the incredible two-headed Martian dinosaur, GaraSharck, sent to Earth. Although GaraSharck put up a better fight then all the Bio-Mecha Monsters put together, even he was no match for Frankenstein.
For his punishment in failing to eliminate Frankenstein, the Nazi Space Vampires teleported GaraSharck back in time to Earth's Jurassic period, where he was to live the rest of his days.
