The one point that I have noticed in most Ranma 1/2 fanfictions (that 
is the ones Ive read) is the lack of a mad scientist character, no 
offense meant to anyone but just think of all the wonderful chaos a 
mad scientist could create (or possibly undo) I mean think of all the 
chaos that Washu (from Tenchi Muyo) caused, in one fanfic Gosunkugi is 
sort of portrayed as a mad scientist, hit me with a mallet if Im wrong 
but he seems too shy and reclusive that and the fact that I couldnt 
imagine him laughing like a madman.  Ive got some ideas on what sort 
of mad scientist would be right for Ranma 1/2 but Id thought it would 
be fun to see if any of you like the idea and or have suggestions

That's easy.  The Kojiro triplets from Futaba-kun Change.
