I know M&M 2e is out of print, but it's the game I collected and I recently opened some books up to make some new characters for a game.
Can I stack Super-Strength? My example is as follows:
I have a character who is strong, but I'd also like her to fly. Due to point costs, I can't have both at the ranks I'd like. A simple solution, of course, is just to make one an AP of the other. However, the drawback is that she can't fly and carry something too heavy at the same time.
Right now, with Enhanced Strength, her effective STR is 30, with a heavy load of 1,600 lbs. If I gave her 2 ranks in Super-Strength, that would up her effective STR to 40, with a heavy load of 3 tons (a medium load of 2 tons). So, with that medium load limit, she could lift and fly a sedan (at 2/3 normal speed).
So suppose I then created a separate power of Super-Strength of 6 with two Feats, costing 14 pp, and the AP of Flight 7, for a total cost of 15 pp. If I were switched to the Super-Strength 6, would that stack with the 2 other Super-Strength ranks so she would have 8 ranks in Super-Strength? And then, if she switched to Flight 7, she'd still have the 2 ranks of Super-Strength that is outside of the Super-Strength/Flight array?
Would that work? It's not breaking any PL limits, but just a way to maximize points to allow her to fly and carry some weight, or be on the ground and lift lot of weight.
