Hooboy... This is a can of worms if there ever was one... I think it's one
of those "Whose universe are we in?" questions, in that Ranma cannot be 
beaten in the Ranmaverse... However, I think he might have a bit of a 
difficult time in A-ko's universe....

Points for A-ko: 

Sheer strength. A-ko is obviously waaay stronger than Ranma, but that 
tends not to matter to much with Ranma, anyway...

Speed. A-ko's pretty quick on the draw when it comes to reflexes. (She 
needs to be, to be able to run like she does.)

Endurance. A-ko can take a LOT of damage without too much ill effect. 
Certainly she has the greater damage capactity.

Ranma's predudice towards fighting girls. This is going to make it a lot 
easier for A-ko until Ranma wakes up and realises that he's gonna need 
everything he's got to take her.


Overall, A-ko is clealry physically more powerful than Ranma in most areas.
The only area where Ranma might have a shot in is quickness...if he wakes 
up and uses it.


Points for Ranma: 

Skill. Ranma is the BEST martial artist you will find in any anime (not 
counting anyone from DB/DBZ/DBGT, etc...). He has toasted some 
pretty powerful opponents in convincing fashion!

Tenacity. Ranma NEVER gives up and his pride will never allow him to 
admit defeat. You can never hope to beat Ranma short of killing him, and I 
doubt if A-ko is up to that.

Creativity. Ranma can always think up a new method of fighting that will
allow him to turn the tide of any battle. Whatever A-ko does, Ranma will
come up with a counter for it.

Experience. Ranma has fought MANY WAY more powerful opponents than 
A-ko. Ranma knows how to tough it out and find an opening in any 
opponents defence. If there's a way, he'll find it. A-ko fights on raw 
talent rather than anything else.

The Result: 

A VERY tough call...

Ranma. Just...

Technique almost always beats brute strength. Even if A-ko can get him, and 
Ranma is VERY quick in his own right, Ranma has way more special attacks 
and other tricks up his sleeve than A-ko. If he is willing to pull out 
all the  stops and fight to his utmost, he'd win by sheer will and  
tenacity. The fact is, Ranma NEVER loses... (not in the long run, anyway...)

Here's another odd little thought.... Is there anyone who could beat 
Songouku?!

P-word.

 
 I think this fight is still pretty one sided. If the fight was to take 
place it will be on the characters base not the universe thing. A-ko does 
like to have a quick fight so if ranma was to actually get the upper hand 
she would Know when to pull back and start throw cars and other things 
and I don't think even Ranma can dodge that for long. Ranma will probably 
have his rematch until he wins and A-ko would get sick and let him win 
for once. A-ko is not one to hold a grudge and anything is better to have 
another weirdo waiting for her every morning.
Gokou huh?
Well he would be hard to beat given that undestructable mosters like Boo 
can't beat him. There is one draw back too the DBverse and that is the 
fight is pretty much one sided punching or Ki. But What if some crazy 
author where to stick a character from somewhere eles, say Ranma and give 
him super saiya-jin powers he just might win given the way he fights.I if 
you think about it not even Gokou can stand 2000 super saiya-jin power 
punches in seconds.
