How to make a animation of defense?

Hi, I would like to know if it is possible to make a defense animation in Mcreator.

In my mod, there's a lot of hand-to-hand combat and I'd like the player to be able to counter the opponent's blows by crossing his arms in front of him, which would play a custom punch sound with 50% damage reduction.
In return, the player who suffers the enemy's blow would move back one or two blocks.
