So we got sight of the Constructicons in ROTF, and see them rebuild Megatron and demolish an Egyptian village and a Pyramid. Now I think it’s time we saw some Autobots take on construction vehicle forms. I’d like to see: - Erector, the G1 crane. Let’s be honest, the minute MBay hears about him he’s going to want him in the film . But still, a crane Transformer would be great and not seen before (ROTF’s Hightower never appeared in robot mode, it was just Devastator’s hand). - Scavenger, the ex-Decepticon bulldozer from ARMADA. MBay’s actually done well with turncoat characters (Jetfire, Sentinel Prime), so this might be a great character for him to use. - Metroplex, the Gigantion excavator from CYBERTRON. Someone previously stated Metroplex would be great as the German bucket wheel excavator. And though it’d be difficult to actually hire/transport/use that machine in a TFilm, I believe it’s a great choice, and would fit his gigantic nature really well.
