Optimus Prime 1980s
The 1980s Optimus Prime is more geometric and has less detail, making him simpler for some people to draw than the 2007 version. The 2007 version, on the other hand, is based in live action and, therefore, is more organic and has more detail. He is, however, hard for some people to draw on paper. Both may be slightly different, but both maintain about the same color scheme: blue and red. And they both have the same alternate form: A semi-truck. I may do another Transformers character in a future blog, but I'm not certain if that counts as cheating or not.
