Wow, this one is rather cool. I was sort of expecting some of the Auroran Robots to not be so nice, and I guess this is one of them.
I also saw on the size reference that Dharma is rather large too. I'm guessing he would be about 25ft tall or something?
By the way, this one looks especially Reaverbot-like to me, and more than Samsara does to me, which I also find cool. In fact, his arms and part of his chest reminds me of Juno Phase 2, and his face reminds me a lot of the Wojigairon Boss, not to mention those buff hammer-like fists make me recall Reaverbots such as the Garudoriten Boss and the Hanmaru Doll. Very awesome!
