I've heard about the subtitle mistake behind Brawl/Devastator's name mix-up. I know who each character used to be in G1, but I came up with a back-story (which will probably never be used in the sequel) so they don't have to change the subtitle. Brawl is a big, beefy Decepticon, and probably feels that his name didn't suit his reputation (the name 'Brawl' is too weak). A few other Decepticons (would later become the Constructicons) that were close war buddies nicknamed him 'Devastator'. He picked up on it, and used the name throughout his life. The only being allowed to call him 'Brawl' is Megatron, although Megatron would refer to him as Devastator. When the Constructicons get word that Brawl is dead, they name their combined form Devastator in his honor (if the Decepticons know any). It even sounds like he says "Devastator" when he speaks, despite not having a voice actor. Even when Megatron shows up in the last fight, he grumbles a few names, and one of them sounds like Devastator. State your open opinion on whether or not the subtitle needs changing or not. I just had this idea to not keep TF fans confused.
