Blue eyes?  Where did you get the idea that Ranma's eyes were blue?  

Frankly I have trouble believing that Gosukungi could have killed
Cologne without her even being in sight.  Killing her to get her
out of the way strikes me as excessively tidy.   

There's a couple I've never seen before...nor will again.  

Nice style.  It's the ultimate in geek fantasies, but hey, I can accept 
the Gosunkugi within me.
