"Hello, this is Julia. Let me speak to the general. Hurry!"
Whoever was on the other end of the line moved quickly. Julia could hear a phone ringing in the receiver.

"Julia, General."
"Yes?"
"I think I've got something for you."
"Yes?"
"If we can transmit a powerful enough signal, we might be able to create harmonics that would interfere throughout the possible displacement area. Interfere with the frequency that closes our bridges, I mean. It's the same principle as concussion affecting the displacement area."
"Wait a minute. Okay, go on. I'm recording this, now."
"If our television and radio transmitters will handle the signal, we can blanket the whole planet with interference. Any mutant that hits it will automatically be deprived of his mutant powers."
