Wow. Interesting thread.
She Hulk as she is now is coparable to Supes in strength. When Jen transforms into She Hulk, her strength grows by an unknown exponent. Multiplying Jen's strength by fifty would cause an incalcuable increase in She Hulk's strength. If she's as strong as Herc or Thor normally, imagine how much stronger she would be if her power was multiplied by fifty before transformation.
If you give Jen the Captain Universe power, which means that she would have super-speed, cosmic blasts, flight, and THEN she turns into She-Hulk, the sheer ownage factor is immense. She'd have Supes on a leash in no time.
