Mental Reservation is the third full-length album by the German power metal band Scanner.

The story is about a young boy named Boris Jay who receives a crystal key from a dark creature.

He returns to Earth as a young man equipped with the instruments of evil, and his political ambitions are immense.

After a year he discovers that evil forces have found a new candidate for their purposes, Albert Twostone, who was one of the prisoners inside the volcano.

The band's leader Axel Julius has stated in an interview several years after the release of the album that the Balkan war was a heavy influence for him.
