That's not it. I mean that it will cause some major threads especially if you paired up some weirdly incompatible characters from other series.

You must understand that in the true verse some opponents are severely incompatible with others. Only in unrealistic and bloated super-power actions can one guy pawn every single person on the planet with one of the most pathetic and over-used abilities ever. Humans will always be different and we are constantly learning and getting more skilled so there will always be someone who can counter your abilities and strategies and force you to change your strategy or run away or get help. Sadly only the genuinely good and well thought out series do this and more times than not it is a mature series since that kind of thing has a lot of gore, otherwise its just people fighting each other with what seems like to be the very same attack with a different colour scheme but same attributes.

This is what happened to DS. Mashima started using the exact same moves with a different colour scheme. At least give them a unique trait that makes them dangerous in a very different way.
