Bio
Soundscream was a Decepticon who was outcasted and made invisible to the others by Knock Out. He was also treated as a droplet in the mist and an unuseful piece of scrap. He eventually abandoned the Decepticons and traveled solo to Equestria to get his revenge on Knock Out by using the Memory Stone. He used the Memory Stone to erase the memories of Optimus from the Autobots and ponies by mistake and decided to use this to lure Knock Out to him. When Knock Out found out, he instantly went to confront Soundscream who was still mad
