I didn't grow up with the G1 cartoon, but I did play Transformers: Devastation, which was based on it. And that Optimus Prime just stuck with me so much. I enjoy the IDW & Aligned OP but man, there was just something so pure about that portrayal. It made me want to get into the Transformers franchise in the first place. I love that character & every time I hear his name I think of his performance in Devastation. That, to me, is Optimus Prime.
