IDW G1 Candidates

Here's an off the wall topic for you:
IDW's G1 inspired series has proven to be fairly liberal in who it includes. We've already had several G2 characters and Gobots cameo in the comic series, and the story-line is set up as another parallel universe rather than as a retelling, prequel, or sequel to any pre-existing G1 story-line.
With that in mind, if you could pick any Transformer from any other TF series to be included in IDW's ongoing series, alongside recreations of traditional G1 characters, who would it be?
At the moment, I'm leaning towards Movie Barricade.
