I still didn't think it was Clockwork on the previous page. The gear motif for a time master isn't exclusive to him- and I think it's fine you used it here since we're dealing with robots.
I agree with you that it's probably Rung. It makes sense for it to be him and I can't think of anyone else it would be. Maybe Rodimus would be a redhead, but Rodimus would totally be a frat boy, not this.
Careful Skippy, it might be one of those tests that determines rather you are a good person deserving of redemption or a moron that would suck on raw sweet potatoes and never cooking them. That or the giant hand is a God like troll that loves dicking with mortals for personal amusement. You'd think they'd get tired of dicking with mortals.
