Two arms and one smile
IIRC, these neck pieces are modular, and the user can add as many or as few as they want. Maybe using fewer would have yielded a cleaner looking dino mode?
THANK YOU! Every time I look at ER Prime, I can't help but wonder how they messed the shape of his robot mode when Siege Prime's robot mode was so much closer to the look of Optimus's cartoon model. It's why I chose to skip both Earthrise and Kingdom's releases and the only WFCT-molded Optimus I picked up was Tenseg Base Optimus (whose robot mode is also much more accurate than ER Prime).ER definitely needs some changes to the bot as well. It's frustrating how off the proportions are when Siege already had them right.
