Flying Thunder God Mutually Instantaneous Revolving Technique

The Mutually Instantaneous Revolving Technique is a technique which requires two persons that are able to use the Flying Thunder God Technique.

Usage
Both persons will mark each other with their respective seals, this grants them the ability to switch their positions at any point in time during a battle. In one instance of use, Minato and Tobirama used this technique to take Obito Uchiha by surprise on the battlefield where Minato — who was originally struck by an attack — switched places with Tobirama to cause the attack to land on their intended target.

Trivia

 * Because of the way that Tobirama and Minato had intended to use this technique to take Obito by surprise, Minato noted that their immortal bodies would be beneficial to them.
