Two foes cross blades in midair
A Combat Trope and a Sub-Trope of Sword Fight. When two foes are sword fighting (specifically when they have high jumping capabilities or the ability to fly) they decide to show off aforementioned flight or high jumping capabilities as well as their ability to swing a sword at high speed. They don't always need to be flying or jumping, this can also occur while the foes are swinging on ropes (or something of the sort).
