I've been trying to come up with an answer for the past 15 minutes, but really, is there anybody from the old G1 roster that hasn't been redefined if they showed up in MTMTE? And for the better, if I might add? Though if I had to chose 1 character, it would be Rewind. After all, Roberts took a character who formerly existed only as a counterpoint to one of the cassette guys, and couldn't really operate on his own away from Blaster, and created a whole new character from the ground up without even removing the aspect of him turning into a form of recordable media. Instead, his character was built off of his alt. mode, since it makes perfect sense he'd actively make use of his internal database to record and replay stuff. Really, it's a shame the best he'll get for a Classics figure is the FoC Frenzy/Rumble repaint as he really deserves better. Roberts doesn't do RID, so he doesn't have control over Arcee. Kind of a shame, since the Arcee/Whirl dynamic would be fantastic, as is anything that has a dynamic relationship with Whirl.
