The following characters are in the credits at the end, but either had no speaking parts that I know of or weren't there at all: Prowl - He's obviously in the movie as we see him die horribly, but he had no speaking part. Dirge - We see him take a mighty shot or two from Prime, but no speaking. Actually, I'm not sure about this one. Is he the one who says "make room for others" as they throw the damaged Decep's out of Astrotrain? If not, who says that? Inferno - Doesn't show up at all. Gears - Same thing. He had the day off. Cyclonus - I can't tell if he's the one who says "The autobots have been terminated" after their spaceship battle. It looks like it might have been Scourge. The voice is similar to Scourge's "you want me to gut Ultra Magnus?" earlier in the film, but I'm not sure. I heard the voice actor died in '86 and Jack Angel (Astrotrain) voiced him in S3, so I don't know. That's all I can remember. Inferno and Gears always stood out to me as a kid. I wish Gears at least made an appearance. Oh well.
