Definition of Power Creep Power Seep:
A character who is designed in his own show, book or universe basically needs to be written to be effective against other characters featured in that show, book, or universe. The concept is pretty self-regulating and self-contained.
However, a problem occurs once you try a crossover. If the crossover involves characters who were never created to work together and have an obvious difference in scope or power, you're stuck at trying to make sure each is effective. This usually involves two scenarios where you either nerf the powerful character or boost the "weaker" one, because you get the inevitable "Why is this guy even useful in this situation?"
Occasionally this fiddling with power levels sticks, and you essentially have a pseudo-Alternate Universe character. Sometimes characters will even get new powers just for balance, but once they go back to their own books these enhanced powers are quickly forgotten.
I think power levels will be fine for the next one, what I AM expecting (and even hoping for) is that some of the newer abilities carry over to the next MK, like SubZ's Ice block move and Scorp's flame aura.
