How Bumblebee Should Have Ended
Soundwave joined the Decepticons in the attack in the fleeing Autobots. Soundwave deployed Laserbeak to attack Optimus Prime, but Prime destroyed the bot, causing Soundwave to cry out in mourning for his pet bird. Soundwave was later tricked by Optimus who had hidden behind the body of Kickback.
