That said, a Summer's sister whose power was NOT some variation on 'energy-blaster', but was more of tank or animalistic / feral or something physical, could be fun.
On the other hand, giving someone a freaky power obliquely related to the whole Punch Dimension concept, but pulling in *matter* instead of red concussive energy, and doing so on a quantum level (so that she's creating more of whatever matter is present, from a strong wind by creating more air in an area, to creating floods by 'quantum enriching' the amount of water present, to causing the earth to rise up and engulf people) could be neat. Every instant, the quarks inside of atoms phase out and are replaced by new quarks, she (insert comic-book pseudo-science bullshit here) prevents the quarks from leaving, but allows the new quarks to appear, causing the matter to double in volume each second, with effects that seem similar to using Pym particles on surrounding matter. When she stops using her power, all the 'extra quarks' rush away and the volume of affected matter withers away to normal almost instantly.
It'd be a fun way to play with the theme of Cyclops power, to draw force from the Punch Dimension, only she'd be drawing essentially proto-matter instead, which assumes the properties of whatever matter is present and expands in all directions, gaining mass as she maintains the power, and fading away when she's done. (Or perhaps remaining until she chooses to send it away?)
