The robot mode is nice though. The proportions are about right. He mainly takes inspiration from the Generations toy and I think the design is even better here, especially with the legs. I also think he looks better in helicopter mode than the Generations version did. The biggest change from usual Whirl look is the head sculpt which I find fascinating. It's length is shortened and while it looks slightly smaller than normal, the cyclopean eye is bigger, for the head. So that gives the head an overall chibi (super deformed) aesthetic. He looks pretty cute for a crazed bot.
In robot mode, the left arm has a similar gimmick to the T30 Generations toy where the claw hand can sprout when activated. The two arms are the only parts that are articulated in robot mode.
Overall, when it comes to a one step toy, this is as good as we have gotten so far, since both modes look rather good.
