Batman series is strickly accurate nor the Ranma series. In
this universe super -powers exist ( they mentioned Superman)
so Ranma may find himself fighting Kryptonians with martial
arts and/or magic.

Even in an orthodox DC universe, human martial artists without
super-powers can give Kryptonians a fair fight.  Wonder how
Ranma stacks up against the mid-sixties Karate Kid (who, by
Superboy's own admission, gave him a good fight when they
first met)?
