M1C18 - Energy Released

<Oh, the Veleek is not one of us,> Visser Three said. <He is not a Controller. He's not
really "he." There is no intelligence there - or at least not much. Fascinating life-form,
really. Unlike anything we've ever found before. It spreads through the atmosphere as a
dust. Each particle can sense life-form energy - any life-form. When one particle senses
prey, the millions of particles come together to attack the life-form and chew it into shreds.
The energy of each shredded bit is then absorbed by the particles themselves.>

Visser Three laughed again, soundless, but vile in my mind. <We lost a lot of soldiers
before we figured the creature out. Oh, yes. It was chewing up Hork-Bajir and Taxxons at a
startling rate. But then we realized something - it could be altered. We could use the thing. I
could program it to serve me.>

I nodded, understanding the truth. <You changed it to detect only the energy of morphing.>

<Very good. But you Andalites always have been clever when it comes to science. Yes,
now it detects only the specific type of energy released during morphing. But it cannot feed
on that energy. Oh, no, no. I didn't want it to shred you Andalites. I didn't want it to eat you.
I wanted to have you here. With me. So I programmed my Veleek to eat only the energy we
feed it from the engines of this ship. Clever, isn't it? The Veleek senses morphing, attacks,
but brings the morpher to me in order to get its true food.>
