Booster X10 (Movie Real Gear)
"Uncover one of the most closely held secrets on Earth, known only to very few humans. The power of the Allspark has been unleashed, and machines all over the world have come alive. Unlock their secrets and join the battle! BOOSTER X10 is a mean-spirited trickster with a talent for toying with people. Sophisticated hypersonics allow him to distort any audio signal, even simple speech. His favorite trick is to wait in his victimís pocket and alter incoming sounds to cause accidents and arguments. He loves seeing how much trouble he can cause just by changing the sound of a word here, or making a racing ambulance sound like a barking dog.
