I have a few.
Jolee: Eh, You Do It.
As someone said already, it's pretty fitting to his character how he's just like "meh, you got it kid".
Zaalbar: Power Blast
Looks cool how he sticks Bacca's Blade into the ground to whip out the bowcaster for an explosive blast.
Dooku: Master of Makashi
One of his signature poses from the movies and tv show. They nailed the animation.
B1: Blast Them!
Captures the feel that you're fighting an army of them without just copying how NS Zombie is.
Visas: Piercing Strike
The behind the back stab is very unique. Too bad she's not really useful of a character.
JKA: Overpowering Assault
The new animation does a great job of capturing a raging Anakin.
As you notice these are all newer animations. They make the older ones look boring in comparison, IMO.
