Ken Christiansen posted a picture on FB of the concept art for Twinferno showing the differences with the final toy.
Awesome ! I love how it emphasizes the weird combination of robotic mechanical parts with organic limbs.
Interesting how little it actually has in common with the final TR toy. (looks closer to the G1 toy really) Neat how the concept appears to allow for pretty well-articulated monster arms (and ankles)
Interesting to see how the design started out, it\'s one of my favourite TR figures. Does have a decent resemblance to Fangry in the body though.
