Sabin kick ability

All I know is that appears to be the sprite that is among the Esper sprites is the animation for Sabin's TigerBreak, which is what Eternal Crystals must be using for the kick skill:

You could try re-spriting it to be Yang... but I can't remember where or how the palette is loaded for it, since it is all black in the sprite editor... I'm also not sure exactly what Eternal Crystals did for the Kick skill, in terms of if it is indeed TigerBreak's animation 100% or if anything else was done to it. From that pic it looks like it might be something left over from TigerBreak that is no longer associated with the Kick skill...but I'm not sure. But the palette for it doesn't seem to be the palette used for TigerBreak, so I'm currently at a loss regarding that.

With RotDS we made it so Tifa has a Kick skill, and we had to change that black silhouette to be Tifa. But again not too sure where the palette for it is, I once knew!
