Hulk Reset to Destroy Everything Mode
Things were getting a little too cozy for Bruce Banner / The Hulk, thanks to recent events, the Army et al. were actually going to give him two seconds benefit of the doubt before obliterating him.
But never fear, The Stranger (remember him from X-Men #s 11 & 18? Yeah, neither do I) shows up looking and dressing and wielding powers of a demon, but all cloaked in the guise of an alien with super advanced technology, to turn Hulk into an even more single-minded engine of destruction, so that he will wipe the planet clean of civilization - and most of humanity - so that The Stranger can rebuild the place better... or something like that.
Anyway, The Stranger has pressing business in another galaxy, so he takes off after doing that.
And really that's the whole issue - Stranger comes - makes Hulk meaner - leaves.
Sooo.... uhm.... yeah.
