First up is Bugly, He had a strange bug for a shell. The robot looked pretty cool as far as regular pretenders go.
The robot-yoga pose for him is ok at best lol.
Finback is a fish thing with a pretty bulky looking inner bot.
Robot yoga pose for him is pretty reminiscent of Submarauder and Waverider.
Iguanus is pretty nice shell-wise, the inner bot is...strange looking with the rounded arms and tiny waist.
It's robot yoga pose is better than most, even if you have to add all the wheels to the bottom.
