In DMC: Devil May Cry, you can parry the enemy’s attack and stun them for a shorty time.
Parrying isn’t a separate button or move. In order to parry an enemy’s attack, you just need to press the attack button right as you are about to be hit with damage. You can parry an attack in the air as well.
The time window is pretty small on a parry, so you have to time it extremely well. Sometimes you’ll end up parrying on accident, not necessarily when you want to since it’s tied to the attack button.
