Thundercracker was voiced by John Stephenson on the g1 sunbow cartoons season 1 and some of season 2. In the late season 2 episode War Dawn, he's voiced by Wally Burr who makes him sound like John Wayne. So I figured maybe John Stephenson wasn't available, but then I noticed that Thundercracker made many appearances in season 2, but he didn't say anything. Skywarp, who was standing right beside him, speaks but Thundercracker doesn't. So what happened to John Stephenson? Did he leave for a new job, get fired or die?
