Like, for example
Binacle use Razor Shell

The Binacle in her hair will move, in turn causing her hair to shake. By using her hair as a cloak of sorts, they can hide in it while using their various attacks.

By using Razor Shell, the Binacle will morph into a great claw or blade.

Alright, I think I'll modify Otohime later to not be able to understand Pokemon speech, but retain the wild child motif. Meanwhile, I'll go make Lind and Tachibana.
