Directly from the Botcon reveals, here is the first design from the Generation figures I helped designing.
I worked on these with Joe Kyde. The process was pretty straight forward, so there aren't other sketches of alternate versions.
The kind of rhinoceros was changed for the final alt mode, but I think it was the right choice as it now looks a lot more intimidating than mine!
I loved doing Rhinox, especially trying to capture the right attitude, silhouette and the details form the cartoon, and i'm so happy to see it translated so faithful to a toy!
