In recent episodes of Macross Delta, it is revealed that the Song-based attack of planet Windermere affects “Delta Waves” found in living beings.
That means there is only one valiant figure who can save the galaxy, one who was transported into the future through what might appear to be a freak accident but we know is actually by design.
Philip J. Fry was born with a unique gift. As a result of being his own grandfather, Fry is the only living being that does not emit Delta Brainwaves. If Delta Brainwaves and Delta Waves are the same thing, that means that Fry would be as immune to the Song of the Wind as he is the attacks of the Brainspawn.
Save us, Fry. The galaxy needs you.
