> ...there is no logic to containing a black hole being that black holes don't expand?

Event horizons expand the more mass you add to the hole. This doesn't change the strength of the horizon or the singularity, though -- they are the same from hole to hole -- just the range of the horizon and the gravitational field that starts where the horizon ends. (Incidentally, a "micro black hole," like any micro mass would have a micro gravitational field -- zilch for pull, basically.) But that's moot, as the breadth of the horizon was such that they were being pulled in, and Supermn stopped that, however crazy that may be.

Additional info

Anyway, where do you stand on the issue? Was Hercules' feat truly universal, or even Earth-level, seeing as how the planet he stood on remained intact? It reminds me of the Spectre/Moon issue -- not whether Spectre weighed as much as the universe, but whether he was portrayed as so much a lunar-level in that comic. I say he wasn't, given that he crashed to/fell to/rested on/etc. the Moon and everything was fine.
