Charlie Watson's Cybertronian Form Inspiration:
Charlie has four Maserati forms, the first in her silver, white, and light blue colors, the second in her darker blue and black, the third in her darker blue and silver, and the last just in her darker blue. In these forms, she is known as Butterfly.
Beck Watson's Cybertronian Form Inspiration:
Beck (or Lil' Bee) has two Mustang forms, the first in a design similar to Bumblebee, but with slightly different stripes that would be in his color scheme of green and black. The second, ignoring the color in the image, would be all black with hints of the green where you see light blue in the image. In these forms, he is known as Beetle.
Donnie Watson's Cybertronian Form Inspiration:
Donnie isn't much for change and so just slightly changes her VW Bug form. Her usual look is all red with a black top, with a black windup key on her end for fun, with the change being that she will turn into a convertible. Other than that, she might change into a vintage almost fully black Beetle with red sides when she and Bumblebee bond over their fondness for VW Bugs. In these forms, she is known as Lady Bug.
