This guy was listed in Monzos database leak thread along with Optimus Primal. Maybe the next deluxe wave we havent seen?
I believe they specifically said at BotCon last year that there were no new robots in RB Season 2. -ZacWilliam, which is a shame, as I would have loved to see Hoist or Medix in Guest Star roles...
More Rubble, Less Trouble. Seriously we really need more Rescue Bots, it'd be the only way to get me to start watching it again, Prime was better in this regard for adding new Transformers in the 2nd season.
Of course, saying there are no new robots doesn't mean much, as they might have been holding off on spoilers. Though given the nature of the show and stuff, it's probable they'll stick with the "core four". (Also, it'd greatly amuse me if the robot mode somehow homaged Barney Rubble from Flintstones)
Boulder's long lost brother? (metaphorically obviously, given their claim of siblings being non-existant for them, kinda a lie given Skyquake and Dreadwing but still, an old buddy of Boulder)
A story could be written in with another guest team - they could also bring in others to the toyline to maintain the rescue theme after the main guys turn into dinosaurs. I see no reason not to make more characters even if they are not in the show - Dani's new Boyfriend seems an ideal partner to Medix for example.
Huh. A construction vehicle seems cool, but hardly "rescue" (then again, there's Boulder, so...). Either way, my nephew will be thrilled since he loves construction vehicles.
