how to make enemy use another animation on attack

so i have searched everywhere for answers on this but i can't seem to make my enemies use other animations when they attack like a sword wielding enemy uses hit animation when he attacks all the time same as a dragon and it just looks stupid like at the picture

I think this script by Yanfly would work in RPG Maker VX Ace for default normal attacks, I am not 100% certain however.

You will need a script though, otherwise the only other option I think is to create a new skill that has the same formula as the default normal attack and change the animation then apply that to the enemy as it's normal attack skill.

give them different skills, and have the skills set to the animation you want.
