The Big Guy and Rusty the Boy Robot (1995) began as Frank Miller's and Geof Darrow's much more family friendly collaboration after the energetically demented Hard Boiled. The Comic was a big over the top tribute to Silver Age comics, Godzilla and Astro Boy. The story is about a giant, primordial monster unleashed upon Tokyo which the military is unable to defeat; subsequently the government is forced to send the newly developed and inexperienced Rusty the Boy Robot in to try and neutralize the threat. Unfortunately he is also overwhelmed by the monster and the government calls on the aid of their American allies who send in Big Guy, a bigass humanoid robot, with two fists and a whole lot of guns. The comic was adapted into a cartoon that ran from 1999 to 2000.
Tropes from the comic:
A God Am I: What the giant monster desires most, to rule over humanity, forever.
The Corruption: The monster's salivary fluids work on a biological and molecular-level. Transforming whatever living or non-living thing it comes into contact with, into an extension of itself.
Defiant to the End: The demon monster. Even after being hurled into the ocean, about to be vaporized by an atomic blast, it roars defiantly.
Did You Just Flip Off Cthulhu?: The pilot of Big Guy fakes his own forfeit to the giant implacable monster. The monster in turn informs the human he and the rest of mankind are fortunate he's a forgiving god, who proceeds to absorb him. The pilot then, smacks the demon right in the chops, sending him flying through several buildings.
Square/Cube Law: Never mind the giant city-destroying monster, Big Guy should not have been able to lasso the fiend and hurl him into the ocean with a commuter train. Even if such a feat were possible, one of the couplings would have snapped from being overloaded by the giant's weight.
