Probably the most notable things from issue 33 is the first proper telling of Batman's origin, but as to the story itself Kruger is a mad man obsessed with Napoleon. He also has airships and bombs Gotham to rubble.

He has a neat visual certainly, and his schemes are certainly big scale. No blackmail here, no, he's going for wide scale destruction. The Batman, and his Bat-gyro, make short work of him and by the end of the tale he's stone dead.
