The official Transformers War for Cybertron site has updated it's character roster! Added to the Autobot side this time are two new additions, Sideswipe and Jetfire! The Decepticon side only gains one new member though, the Decepticon air warrior Thundercracker. Thundercracker remains the slightly conflicted character described in his original tech specs and seen in All Hail Megatron. Meanwhile, Sideswipe's bio stays true to his "I don't break the rules, I bend them... a lot" persona from his Generation 1 portrayal, although Jetfire has undergone some small tweaks. He's now the fastest of all the Autobots, and is also one of their main science guys. His bio implies his backstory tie to Starscream will still be present in some form, though.
