Totally random thought - what if Takamaru had a move mimicing when two Samurai charge toward each other and attack at the same time, like in movies or whatever, and then there's the delayed reaction to build the anticipation to see who got hit as they stand facing away from each other a few paces apart in their attack poses, and finally somebody falls down, wounded. So Takamaru charges, attacks, whatever kind of woodwind instrument it is you always hear in Samurai-related media blows dramatically, then the opponent suffers a delayed bit of knockback. Maybe they even add some cherry blossoms and the sound of wind blowing in his wake just to make it more cliched, awe man.
I don't know how this would be at all useful, I just thought it sounded cool
I've also been trying to think of some way to work Tanukis into his moveset, buuut I'm not really a moveset guy, as you might be able to tell by my confusing description of a probably crappy move above
