(What the hell ever happened to Cho, anyway?)
Anyway, there is at least one case that young Amadeus seems to have missed. Having just finished a dust-up with Dr. Doom, the Hulk is trying to swim home...but he is spotted by a Russian naval destroyer:
Well, Hulk dragged the entire ship underwater, to crush depth, and all the munitions exploded.
Still sticking with "not a single soldier has died," Mr. Cho?
And as the Hulk swims away:
The Hulk swims so hard that he makes a tidal wave hit the "unprepared coastline."
Still going to insist that no innocents were ever killed by the Hulk, Mr. Cho?
Yes, I realize that I am the only person in the world who cares about this...
From Incredible Hulk #145 (1971)
