And Optimus Prime has gotten practically no character development. He's still the same statue he was at the beginning of this series. He almost hinted at being less than perfect and showing some emotion in the last episode when he pointed his blaster at Starscream and commanded him to lead him to the relic "regardless". He may have shown some emotion in "One Shall Fall". Other than that, the only time he really showed emotions is when he...wasn't himself (Orion Pax). Come on Prime. Even in G1 you had a little more personality.
