How to make character fight with another pawn

Hi!
How Can I make my character interact with another pawn, at the same time the pawn itself response to the action.
For example, a fight between two characters. Like Batman Arkham Knight.
And, let’s say I have the fight animations.

How can I make it possible? Maybe some basics idea on how they response to each other might help a little bit.
But, a video that could explain about this will be wonderful!
I’m talking about the blueprints and other stuff which involved with this.

Theres alot of blueprinting that goes into this. I have a tutorial series for melee weapons that might be helpful to you Vice Versa Studios - YouTube
