Bumblebee(2007-2009)The 1980s Bumblebee, like 1980s Optimus Prime, is more geometric and simpler to draw than his 2000s counterpart. The 2007-2009 counterpart, like 2007-2009 Optimus Prime, is more organic/mechanically detailed than the 1980s version and more difficult to draw. They are similar in color, which is Yellow.
However, unlike Optimus Prime of both eras, the two Bumblebees are two different vehicles. The 1980s Bumblebee is an old Volkswagen Beetle. However, due to licensing issues, the people behind the movie had to replace the Beetle with a Chevrolet Camaro. The Camaro had the black stripe coming down the middle, which matches the stripes of a bee and is more fitting to his name.
Hopefully, these entries are good so far.
