>>6007250>What does Bay Starscream have in common with the conceptual Starscream?The name and personnality.
Bayformers are meant to be credible and they were in the first movies until they tried to make them look like knights or something. The "conceptual" designs can't be turned into something realistic, that's just plain impossible and none of the fanarts "proving the opposite" is even close to look like something that could exist as an extraterrestrial robotic lifeform.
You're free to dislike these designs but that doesn't change the fact using them for a realistic movie was the right decision.
