Fan Casting Bash Brothers in Sort by Tropes

In action oriented stories, two characters who are friends will work with each other during combat. Often this will present the image of Back-to-Back Badasses. If one person is big and the other short, the big guy will use brute strength and the short guy will use finesse. Maybe the big guy will clasp hands with the short guy and fling him around as though he was a weapon. Or the big guy will use the short guy as a projectile. No matter what, they will fight in tandem. They will watch each other's back. There is something genuinely satisfying about watching the heroes take out a room full of bad guys by working together.
