The Big Picture

Mad Thinker devised a plan with numerous criminals inside the prison to escape by using a reducing gas to decrease their size so they could stow away on She-Hulk's skin. Hank Pym used his re-enlarging gas to bring Southpaw back to normal size but the residual fumes increased the size of the criminals hiding on the emerald beauty by a few inches. Powderkeg and the other criminals ran off but they were all trapped inside the office building due to an impenetrable force field that was activated.
