It's fair to say while many robots in the movies are based on G1 characters (the five Autobots in the first film, Megatron, Starscream, Soundwave, Jetfire, Arcee, the Fallen, the Constructicons) there also a great many who aren't, and please don't confuse trademarked names that have been avaliable since the 1980s with characters. Skids, Mudflap, Brawl, Bonecrusher, these are characters included because Bay wanted to see those vehicles as robots. According to DVD, Scorponok was included only because the writers liked the idea of a robot scorpion, which is why he has nothing to do with Headmasters. I'd like to see: 1. The aircraft carrier Bay still hasn't included. 2. A space shuttle. 3. An iPod.
