The Stratos Tournament is a tournament that takes place in a dimension known as the Mirror Field. The winner of the Stratos Tournament is rewarded with a wish of anything the winner wants. The tournament was originally created to control the Mirror Field from taking over the real world, the reason for this was never revealed.
The Stratos are giant humanoid robots that can only be activated in the Mirror Field. Each Stratos pilot has their own unique Stratos with their own names and abilities. A Stratos is controlled by the movements of the pilot, meaning that the Stratos moves the same way the pilot moves and thinks, this system is called the trace control system. The pilot controls a Stratos in a cockpit which is an orb that shows the sight of the Stratos. The pilot is given a trace armor of his or her Stratos, making the pilot feel as if he or she is the Stratos itself.
The Mirror Field is a dimension inside of Earth that only a Stratos pilot can use a portal to enter. The Mirror Field is also sometimes referred to as the Stardust Field because of the sky showing the galaxy above the clouds and daylight. The Mirror Field is a reflection of the real world with the exception of the sky showing the galaxy, even though it is a reflection, the only people allowed to enter are those with a special connection to the Mirror Field and no one except the champion is allowed to stay in there unless there is a battle but are allowed to travel through it for a set amount of time. For each hour that passes by in the Mirror Field, only a second is passing in the real world.
